We stayed at Carla's flat for 3 days. The flat has two bedrooms and two bathrooms and I think it is perfect for accommodating 4 people. Carla was very helpful with everything. I really felt like I was staying at a relative's place. The neighborhood is so lovely as well. It is very close to Campo Santa Margherita which is probably the most beautiful square in Venice. I am planning to visit Venice again sometime soon and I will definitely stay at Carla's place in my next visit.
