I stayed at that appartment for a week and I liked it very much. Actually it's not a separate appartment, more like an appart-hotel, but you can feel free like you stay at the real flat.
Marco and Antonio were very kind and nice. They both helped me to get to the appartment. Marco was always online and wrote me helpful messages. Special thanks to Olga, who helped me with buses to Venice, shopping center and furniture)
The appartment was cleaned every day. It has fully equipped kitchen, excellent wi-fi connection and bath accessories. It's situated in a quiet area, 15 minutes walking from the station, 15 minutes by bus from Venice (the bus stop is in front of the building), 1 minute from two supermarkets. And also Mestre is a nice place to walk.
So it's the right choice for staying in Venice with the normal price.
