Stayed at Palace Bonvecchiati for three nights and enjoyed every minute of it!!! It describes itself as a design hotel and you can see why the moment you walk into the hotel. Staff members were very friendly and helpful. Palace Bonvecchiati is very centrally located; very close to Rialto Bridge and Saint Mark's square; in an excellent position from which to visit the city on foot in the labyrinth of narrow streets and small squares.
This is quite possibly one of the best hotels I have ever stayed in.
