Our family of 4 (2 adults and 2 teenagers) were quite comfortable staying in the apartment. Considering it is centrally located near Rialto Bridge, it was peaceful, quiet and relaxing.
The main reasons for choosing this apartment over others were: location near Rialto Bridge (3 mins away), strong A/C, good Wifi, quiet and safe neighborhood feel, clean and spacious apartment, near Rialto Mercato (buying fresh fruits & vegetables), near restaurants & cafes and near public transportation (3 mins away). Piazza San Marco (12 mins away walking).
My family and I have been to Venezia 3 times already and you really do get a value staying in Alberto's apartment considering the location, area space and price for a hotel in Venezia.
Tips:
Considering we visited during July, A/C is a Must in your room.
If you can budget it, get a private water taxi (120 Euro) from the airport and back (saves you time & headaches & dying from heat exhaustion) from the public transportation Alilaguna.
If you do take Alilaguna, it takes an hour or 1.5 hours to Rialto stop. It's definitely cheaper (15-20 Euro per person each way).
Have breakfast or cappuccino at Caffe Del Doge (#3 cafe in Venezia) in TripAdvisor 15 steps away from the apartment. They have excellent coffee, excellent pastries, even vegan options. It's not only tourists there but locals too. It's a quiet little place to relax and the baristas are nice.
Have lunch or dinner at Trattoria alla Madonna (the next street over). They have been around for many years, they serve fresh seafood and regional dishes. The locals also eat here. The tiramisu is NOT to be missed here. It's one of the reasons, I keep coming back to Venezia.
The apartment has refrigerator, utensils, plates, coffee machine, washer, everything you need in a home away from home stay.
We did not use much of the kitchen as we ate out more, but it is fully equipped to use for cooking.
Since almost all of Venezia has no elevators, be prepared to walk and carry your luggage up 3 floors to the apartment. I have stayed in other hotels and that is the norm.
Note: The shower is a bit smaller than what Americans are used to, but normal for Italians. Also the shower temperature is quiet sensitive when you turn hot, it really turns hot and same for cold. I know we had to find just the right place for it to be perfect temperature.
Overall, our stay at the apartment was excellent. :)
