Listing was as described, clean, safe, and comfortable. The smart thermostats left the temperature a bit odd throughout the house at various times requiring a bit more attention than I'd otherwise give to a temperature setting.
The most glaring concern I'd highlight is the extensive engagement outside of the AirBNB platform. It feels a bit inappropriate for an AirBNB listing to require a signed, multi-page rental agreement with long lists of rules/guidelines. All of the messaging while we were at the rental was outside of AirBNB so I didn't respond as there was nothing needing a response.
All communication and agreements should be done within the AirBNB platform so they can mediate issues if they arise.
In the pre-arrival email, there was mention of downloading a separate mobile app as the "one stop shop" for all things about the rental and if that was mandatory for any component I would've reported that to AirBNB but I was able to get to their guestbook, which is hosted outside of AirBNB, through the links in the email.
In summary - the place was fine and I'd stay there again but I feel it's not best practice to list on a platform like AirBNB and then have a rental agreement and all communication occur outside of the platform. The point of AirBNB is to provide guests and hosts with a safe, secure, consistent platform for renting vacation homes and AirBNB seems to discourage this type of non-platform engagement.
