I have found the apartment at Calle Montello San Elena very comfortable, well-appointed and cozy. The apartment is clean and spacious, equipped with Wi Fi, washing machine, dishwasher, TV etc, which all works well. All rooms are nice and in perfect condition and the living room connected with the kitchen is comfortable.
The apartment is located in close vicinity of vaporetto stop (around 5 min by walk) which provides good communications with all interesting points in Venetia, moreover Plazza San Marco is also in walking distance – around 20 – 30 min by foot from the apartment. The vicinity of the apartment is nice and quiet and include small park. Not far from the apartment there are small grocery shop, osteria, shop with fresh fruits and veggie, pharmacy, and around 15 min from the apartment there is Via Garibaldi with a lot of restaurants, trattorias, cafeterias, small supermarket with deli, as well as stalls with fresh fishes (operating at morning) and fruits and vegetables. Such localization allows for early morning jogging starting from the park along Canale di San Marco to Plazza San Marco and buying rolls at one of bakeries on Via Garibaldi on a way back.
In my opinion, for special emphasis deserve: good localization, very spacious living room, nice and clean bathroom, person who take care of the apartment (she pick up us at vaporetto stop and come to help us with heating system), comfortable beds with good mattresses (important in the case of spin pain), walking distant to the church La Pieta with chamber concerts (each evening!).
