Excellent location, very close to Piazza San Marco. If you come from Piazza Roma by vaporetto is much better to get down at San Marco stop than at Rialto stop that is more far away.
The apartment is clean, tidy, well ilumimated and comfortable. The bedroom isn't big but we put our big luggage in the living/kitchen so problem solved. The bathroom is big, nice and clean. The shower is great.
In the kitchenette you will find everything you need including bread, water, juice, coffee, sugar, honey, etc. The wi fi works very good. The only negative aspects were that as it is in the 3rd floor, for some people it might be difficult to carry upstairs their luggage if it is heavy (we had more than 50 kg of stuff) and the other negative aspect is that sometimes there was like this bad odor, maybe from dampness or humidity somewhere . I highly recommend this apartment.
