01One inbox
Guests from 90+ channels, answered in one Rentals United inbox.
Guests from Airbnb, Booking.com, Vrbo, Expedia and dozens of other channels write into the same Rentals United inbox. The AI agent replies to each one in seconds, inside that reservation chat, with the booking and the property in view, and answers WhatsApp, email and web chat the same way.
- Replies inside each reservation chat
- Holidu and Marriott Bonvoy guests included
- WhatsApp, SMS, email and web chat too
02Requests to book
Requests to book confirmed while the 24-hour clock still runs.
A request lands from Airbnb at midnight and the window to answer has started. The AI agent reads the guest’s message, asks about anything your house rules care about, such as group size or pets, then confirms the request or declines it kindly with your reason, long before time runs out.
- Checked against each property’s house rules
- Kind declines with the reason the guest sees
- Airbnb enquiries pre-approved for free dates
03Arrival day
The right door code for every building, sent on arrival morning.
City portfolios mix key boxes, smart locks and concierge desks. The AI agent sends each guest the entry steps for their own building, the door code and the parking notes on the morning they travel, answers the lift and luggage questions that follow, and says goodbye with checkout steps.
- Entry steps written for each building
- Door codes for confirmed guests, on time
- Checkout steps and thanks on the last day

Confirm Airbnb and Booking.com requests to book in Rentals United
When a request to book arrives, the AI agent checks the dates in your Rentals United calendar, reads what the guest wrote and asks one friendly question if something is missing. It then confirms the request, or declines it with your reason and a kind note, and your team sees every decision in the inbox.
Customer: We’d love to bring our small dog. Would that be all right?
AI agent: Small dogs are welcome at Canal House, so I’ve accepted your request. A bowl and a blanket will be waiting.
-
Send each Rentals United guest the right building’s door code
On arrival morning, the AI agent picks the entry steps for the guest’s own building from your property notes, then sends the door code, the key box location and the parking details in the reservation chat. Guests who ask days ahead are told exactly when it will reach them.
Customer: Which entrance do we use? There seem to be two doors.
AI agent: Use the glass door on Rivington Street. Your code 4417 works from 3pm, and the lift is on the left.
-
Reply to Airbnb, Booking.com and Vrbo reviews from Rentals United
Each new review in your Rentals United inbox gets a reply in your tone within the day: thanks for the kind words, a calm answer to any complaint and a detail from the stay, so it never reads like a template. It goes live straight away, or waits for your approval if you prefer.

Made for portfolios on Rentals United.
Built for teams who answer guests across many cities, channels and brands at once.
-
Every channel answered the same way
Airbnb, Booking.com, Holidu or your own website: guests get the same quick, accurate answers, whichever channel the booking came from.
-
Italian, Arabic or Dutch, answered alike
Guests write in their own language and get a reply in it, while your team reads a translation in theirs.
-
One voice per brand or region
Run several brands from one account, and each keeps its own tone, sign-off and welcome.
-
Answers drawn from your own content
Each reply comes from the reservation, the property content you keep in Rentals United and your notes, so the guest in flat 12 never hears about flat 14.
-
The duty team, briefed in advance
Damage reports, refund questions and late-night emergencies reach whoever is on duty, with the booking and the full chat open before they reply.
-
Teams in every city, on any device
Guest teams in Lisbon, London or Barcelona follow the same threads in the MessageMind apps on iOS and Android, or on the web.

Rentals United AI integration: questions and answers
Is there an AI agent for Rentals United?
Yes. MessageMind’s AI agent plugs into Rentals United and works the guest side of your channel manager: it answers every guest in the Rentals United inbox, handles requests to book, books direct stays, sends arrival details and replies to reviews, around the clock.
Can an AI chatbot answer guests on every channel I sell on?
Yes. Rentals United gathers messages from more than 90 booking channels in one inbox, and the AI agent answers each guest there within seconds, from Airbnb and Booking.com to Holidu and Homes & Villas by Marriott Bonvoy. Every reply stays in that guest’s reservation chat.
Can it accept or decline requests to book for me?
Yes, by the rules you set for each property. Airbnb, Booking.com and Vrbo requests are checked against your house rules and calendar, the guest is asked anything you need to know, and the request is accepted or declined with a polite note, well inside the 24-hour window.
Can it take direct bookings and change dates?
Yes. Guests who write from your Rentals United website or WhatsApp get a quote with your length-of-stay prices and discounts, a secure payment link and a confirmed stay. Date changes and extra nights are confirmed in the thread whenever the unit is free on every channel.
Does it send door codes and arrival details?
Yes. Each property’s entry steps, door code, key box and parking notes go to confirmed guests on the morning they travel, in the reservation chat or on WhatsApp for direct stays. Guests who ask early are told when everything will arrive.
Who decides what the AI agent handles on its own?
You do. For each brand or property you choose which topics it settles on its own, from arrival questions to requests to book, and every reply sits in the Rentals United inbox for your team to read.
Does it answer guests in Spanish, German or Arabic?
Yes. A guest who writes in Spanish, German or Arabic is answered in that language, whether they booked a flat in Barcelona, Vienna or Dubai, and your team sees a translation of every message, so anyone on shift can follow along.
Who connects Rentals United to the AI agent?
Our team does it with you. We link your Rentals United account, go through each brand’s tone, house rules and arrival notes, and you pick the channels and properties where the AI agent starts answering first.
What does an AI agent for a Rentals United portfolio cost?
Each MessageMind plan comes with its own channels, monthly credits and team seats, and the plan you choose sets the price. The pricing page lays the plans out in full, and our team can size one to the units and channels you run.
Is guest data safe across so many channels?
Yes. MessageMind runs on servers in Germany under GDPR and encrypts data in transit and at rest. Rentals United stays the record for every reservation, and door codes reach guests whose booking is confirmed, at the hour you choose.
More units, more channels, the same quick answers.
