We were in room 55, not 66. So this is a review for room 55, though I assume they're similar.
The bed was terribly uncomfortable, caused a fair bit of back pain. Felt like sleeping on a box spring rather than a mattress.
It was further out than we expected, its 20 minutes to Venice. But an hour to anything worth seeing or doing in Venice.
The room itself was very clean and very well organized. It had everything we needed and then some, and the local tips provided were great. Great communication with Jelena and she was quick to fix the AC for us when it stopped working.
A great stay if you don't have back issues and don't mind a slightly further commute.
