We enjoyed our stay at Leone's place. He was a wonderful host, explained everything, provided more than expected, and communicated very clearly. The space is small and compact, but has everything. It is well laid out and in the heart of the city.
The only surprise was that the couch folded out into a bed. However, it was very comfortable and we slept well. Every square inch of this space is utilized in a creative manner and Leone has special touches throughout.
I would recommend Leone's place to stay when in Venice.
