Al Palazzetto is in a lovely old building (I think the owner told me it was 380 years old). In a quiet neighborhood, very close to the Ca' D'oro and the Strada Nova shops. If you need something from the pharmacy or grocery store, it's only steps away.
Our room was beautifully decorated (venetian tapestries, antiques) and for the most part, very comfortable. It was a wonderful refuge from the hot, crowded Venice walkways and vaporetti. In fact, I felt a little guilty for the amount of time I spent in the room instead of exploring Venice. It was just so pretty and peaceful. The bathroom was updated, bright and clean. Everything worked, except for that the shower drain was so slow and we were limited to very short showers before the shower pan overflowed onto the floor.
There was a mini-fridge in the room, which was a great convenience.
We had insufficient air conditioning our first night, but that might have been our own fault for not knowing how to use it. Wifi was weak to non-existent. If you really need wifi, I'd suggest not staying here.
The breakfast was very nice. Fresh croissants.
I had some issues with hospitality and should probably admit that I'm more of a full-service hotel type person. When we arrived, the owner seemed very uninterested in providing a basic orientation. She tossed us a ring with three keys on it and seemed in a rush to return to her living quarters. My family and I wondered if we'd done something to offend her. (The three keys were not labeled so it was a bit of a juggle to get back into our room after wandering around. Also, you get just one set of keys so if you and your travel mates do separate things, you'll need to coordinate. Cell phone reception and wifi in Venice are spotty and there's no "front desk" that can keep the keys for you). I didn't visit the Rialto Market in the early morning, as I had hoped, because I wouldn't have had a way to get back in my room.
The hospitality issue had other impacts for us. When the air conditioning and wifi were insufficient, we didn't feel there was anyone we could approach. Every time I asked a question I felt like I was irritating the owner. They were the coldest people I met during my two week (4 city) visit to Italy.
