The apartment itself is clean and lovely and obviously well cared for. Once we were inside the apartment we enjoyed it very much, in particular the air conditioning, which is important in Venice with so many bugs and so few screens.
It must be known to those who rent on Airbnb that there is not a "Massimo" who owns this apartment. Instead this is an apartment rented out by a company with over 100 apartments. They have very clear policies on their regular website about check in. However, it must be noted, that here on their Airbnb site they make no mention of specific check-in procedures and yet they expect you to know what to do!!! We booked an apartment for the following night, and when I sent an Airbnb message at 10 am the next day to find out what to do at the 2:00 check-in, no one responded!!!! I used the google map directions to find the apartment, with no one waiting for us. I messaged the number listed on Airbnb and someone finally wrote back but with very cryptic answers and we thought perhaps we had been scammed. Finally someone came to meet us at 8pm!!!! 6 hours after check-in!!!! We lost 6 hours of time in Venice and we were quite worried the whole time that no one would actually come. The man who arrived and showed us the apartment was nice and professional but did not seem very apologetic for having made us wait so long.
In addition it should be noted that there is an additional tourist tax, which is not listed on their Airbnb listing.
I recommend that of this company wants to continue to list on Airbnb, that they make the check-in procedure clear and easy.
