Lorenzos apartment is perfect for a trip to Venice: The quarter, San Polo, is in my opinion the best of the six quarters of the city: Very central, but not too crowded! You can reach almost everything by foot, the next Vaporetto station, San Tomà, is a 5-minute-walk.
The communication with Lorenzo was really easy, he answered our questions very quick and precisely.
Very nice is the terrace of the apartment; we had wonderful weather and could sit outside in the evening and have a drink.
One bedroom of the apartment - the one with the double bed - is very spacious, the other one is quite small - maybe a little bit too small for a tall adult (for us it worked), but it would be perfect for a child.
The only (small!) problem we had was with the water: It takes quite long until it gets warm/hot but after a while we got used to it.
All in all I can recommend Lorenzos apartment sincerely!
