Reviews for Grappa's places
It's a nice place. Rather remotely located (walk to San Marco takes about half an hour) but very quiet and peaceful, and easily accessible. Exactly what you need during noisy carnival. We (family with two little kids and a cat) enjoyed staying there a lot. It is better than any hotel room of the same price, of course if you like to feel like at home. The disadvantage - it is located on the third floor and the stairs are quite steep and narrow.
Good value for money. Can only recommend it.
