Marco's place was very nice. We traveled to Venice for the Biennale and we were very happy with the location of the apartment, in between Arsenale and Giardini, few minute walking from each. The area was full of coffee shops, pizza places and there was also a super market close.
The apartment is very nice, with a spacios bedroom and a fully-equipped kitchen (devices, coffee, even small ciocolate :) ). Marco was very responsive so it was very easy to keep in touch whenever we had questions. We recomend it :)
