Me and mum stayed at Alberto's for five days.
The apartment is in a great location. Right next to the grand canal, a co-op shop one street away, and five minutes from Rialto bridge.
It's a spacious apartment with a lot of room. There is room for six people, but four people would be very comfortable in the apartment.
All in all, we were really pleased. The WiFi was slow, but that was a minor inconvenience as we were out most of the day anyways.
