We spent a wonderful week in Roberto's place. We found his communications quick, clear, and helpful before we arrived.
Once arriving in Venice, we were met by Roberto's friend Rudi, who was helpful and full of information. He gave us a short tour of the apartment and the area to make sure we could make ourselves at home.
The apartment itself is an absolute treasure. It's well laid out and beautifully furnished. Instead of an all-Ikea apartment, or something furnished with someone's grandmother's old things, this apartment was furnished with thought and care. Linens, towels, decor, and furniture were are all lovely, in a way that someone might furnish their own home rather than a rental suite. It was also spotlessly clean, which was both recognized and appreciated.
We were pleasantly surprised by the large, private, gated outdoor space, which was perfect for kids to play safely. The kitchen seemed small at a glance, but it turned out to be extremely well equipped and we ate many meals at home without difficulty. The location was terrific: very close (30m?) to a bustling thoroughfare with every amenity you could want, but on a quiet sidestreet overlooking a canal. Even during the craze of Carnevale, we couldn't hear the noise of the crowds.
I cannot recommend Roberto's place highly enough: between the great support of Roberto and Rudi, the superior quality of the apartment, and the excellent location, I would say it was one of our best AirB&B experiences ever.
