I can absolutely recommend staying at this place.
The location is great, close to the waterbus station and easy to reach from both airports, the Treviso and the Marco Polo airport. Furthermore, it is very close to the city center and the Rialto bridge, but still in a very calm and untouristic neighbourhood.
Bjorn is a great host! He picked us up from the waterbus stop and gave us a lot of advice and suggestions for our time in Venice.
The apartment is perfect as well, very clean and pretty small, but you have everything you need. Bjorn provided us towels and we could even do a late check-out.
Communication is very easy and quick.
All in all, perfect :)
