Great apartment. The bedrooms are a good size ( we were travelling with a family of 4 with 2 kids aged 5 & 7 but it would equally suit older kids). Downstairs is small & cosy but we spent so much time exploring that we didn't need a larger living area. There is also a nice garden area, which if we had more time in the city we would dragged a chair outside to sit.
Luigi was very kind and hospitable and made sure we felt at home.
The apartment is in a great location for walking to the big sights but off the beaten track. It feels quite local.
As a final tip we managed to get there using the bus from the mainland, then the Vaporetta to S.Zaccaria, then a short walk to the apartment with kids and luggage, in a thunderstorm. Surprisingly easy because of the location and info provided by Luigi beforehand.
