The airbnb is nice and spacious, very well suited for stays longer than just 2 nights.
All in all we had a good stay and we liked the apartment.
However, there were definitely some points we didn't like at all.
The apartment wasn't really clean. The floor was dirty (you had to wear shoes inside) and the dishes were washed poorly. If I have to pay a cleaning fee, I expect it to be clean, as if I cleaned by myself.
Then the communication with the host(s) was also a bit confusing. They asked us to communicate over whatsapp instead of airbnb, which is not how it is supposed to be. Then we had to text 3 different people somehow. The third one was the one that did the checkin with us. She was very much in a rush and didn't really seem to know the apartment that well.
Furthermore, after getting the confirmation from Davide, that there are no spices like salt, pepper and other necessary things in the kitchen to prepare food we bought everything in advance. After we arrived and had a look in the shelves of the kitchen it was fully equipped with almost everything you need. The only way I can explain this, is that the host has not been in the apartment for quite a while.
The last point we have to mention ist the location of the apartment, however, this is a very personal point of view. The location is very good if you wanna visit San Marco, Rialto or Dorsoduro. For all the other districts of Venice you will have to walk quite a while. This was not very convenient for our stay of 6 nights.
