My wife and I stayed at the Londra Palace on a trip to Italy for our 10th wedding anniversary, and found the hotel outstanding. We stayed in a spacious junior suite on the 4th floor (Room 410). When we arrived, there was a bottle of champagne waiting in our room, on ice, compliments of the hotel. Our room had a beautiful view of the lagoon, and the view was unbeatable. The noise from below was not a distraction (the four windows were very well insulated). The room was luxurious, and very comfortable.
The staff was friendly and helpful, helping us to make dinner reservations, find transportation, and to help us navigate Venice (beautiful city). I would go back to this hotel and easily recommend this hotel to anyone visiting Venice.
