I visited Venice with my grandmother and my aunt for four days and this flat has everything we needed. It is huge for a Venice apartment; two enormous rooms (with awesome beds), two complete toilets (even with bidet!), living room and dining room and a small but comfortable kitchen.
All the apliances are new and work great. The water heater is automatic and the water pressure is good. It even has a thermostat in the living room, so perfect temperature all day and night.
Matilde and Matteo were amazing hosts. They were waiting for us at the vaporetto stop and helped my grandmother with her luggage. They recieved us with a wine bottle and also prepared a folder with info about Venice and the flat (wifi password, their phone numbers, a turistic guide, a map...).
I would totally choose this flat again for my next trip to Venice.
