I can't recommend Doriana's place enough! She is incredibly sweet, and made us feel like family! I would stay with her again in a heartbeat!
The room itself is incredible. It has a really cold AC, and after baking in the hot Venetian sun, it was a welcome retreat coming home every day. Everything was sparkling clean.
Last note: the location of the place is unbeatable! You're at the heart of everything. The entire trip, we were usually 10 mins walking from anywhere we needed to be. Also, if you land in the main venice airport, you can actually take a water taxi and land a few minutes from her house. Things could not have been more convenient.
