Very nice location between Arsenal (less than 5 min) and San Marco square (about 10 min), at a small and silent corner, away from the crowds. Apt is on 1st floor, with private entrance and staircase. In September the apartment is fully shadowed all around a clock, so if you'd like to avoid a sun heat, this is a perfect choice. You may also use the air-conditioning.
It had everything we needed.
We found the shower enough comfortable. 1 minor thing: the water splashes outside from below the shower door, so the provided foot step towel was not enough and we sacrified one of towels for the bathroom floor but don't worry, they provide many towels.
Marco was extremely helpful, providing all necessary support and tips. Although he was waiting for us at the water stop in the evening, we did not have to pay any late check-in fee.
In overall we were very happy with this choice and we fully recommend the apartment and its host.
