I really enjoyed my stay at Sandro's. The place was beautiful, very comfortable, with hardwood floors and lovely lighting. As others have mentioned, it is on the 5th floor, and that allows it be above the noise of the street. It serves like a comfortable sanctuary after the business of the (rightfully) crowded tours of the day. Everything was clean, comfortable and thoughtfully laid out. It is located only a few blocks from the Cathedral Santa Maria, L'Accademia, and the Museo San Marco. Despite that, I found the noise from the street to be minimal. Sandro himself is a delight--very helpful, with good recommendations for what to do, see, and any logistics you may need. I would highly recommend staying here. I'm looking forward to doing so again in the near future.
