We enjoyed staying at Giovanni's place. He was very responsive and was helpful when I asked for a suggestion as to where to park and how to get to the apartment from the parking lot.
His place was clean, spacious, and we appreciated having two bathrooms. He also provided a list of suggested places for food (breakfast, lunch, dinner) which we took advantage of. The apartment is in a very convenient area (close to Rialto Bridge and San Marco) with great breakfast and dinner options literally around the corner.
Staying at Giovanni's place made our first trip to Venice a wonderful and memorable experience. We would stay there again.
