Federica is a great host and the apartment is exceptional! For an apartment in Venice, it is very bright and very modern. It is conveniently located right in the middle of Venice, so great for exploring the city. However, it is also very, very quiet. Sometimes you can hear the Jazzbar on the street, but only a little and they never played music longer than 11pm.
Wifi is great (we tested 300 Mbit/s download!). Communication with Federica was very easy and we always got a quick reply, when we had any questions.
