Federico was very responsive and helpful the entire time, up to and during our stay at this apartment. He met us at the bus stop as planned and walked us to our apartment (it was already late at night). He then gave us a comprehensive crash course on a map of venice and the sites to see and the best restaurants on offer. This was immensely useful.
Apartment was clean and well prepared for our arrival and we had no issues the whole time we were there. Apartment was exactly as advertised and everything was nearby/within walking distance (i.e. 15-20 mins max). The free wifi was clutch if you don't have cellular internet.
We enjoyed our stay at this apartment and recommend it for others as well.
