The bed was a little creaky as others have commented, but considering the other good points, this room is worth more than the price and I recommend it.
The location is very convenient, 5 minutes walk to the supermarket CONAD and station of vaporetto, and less than 15 minutes walk to the Accademia museum.
Check-in was very easy and smooth, and the three keys were numbered to make it easy to know the order in which to use them.
We communicated with the host only through messages, but she was always quick to reply and recommended restaurants before we arrived.
Thank you very much.
