Room is conveniently located in a not too busy area but close to San Marco square which is nice. It also has everything you need for your stay as long as you don't mind to share the common spaces (kitchen, bathroom and living room).
The check in process could be made a bit easier since it's possible only between 3pm and 7pm in a hotel situated 5 minutes walk away. There is basically one small reception and, since it look after the hotel itself plus it manages check ins for external rooms, it can get pretty busy and it takes time to pick up the keys.
In our case there was a queue waiting for pick up keys at 3 pm and we waited 40 minutes. The receptionist was although very nice.
Overall good experience for the price paid.
Also cancellation is not possible so keep that in mind.
