We were supposed to meet Nicola at 2:30 at the Arsenale stop, but after 45 minutes of waiting, we started to panic. So we had to call him (could not find wi-fi nearby) and incur an international fee because we did not have an international plan or a SIM card. He had tried to contact us to say he would be late, but we didn't get that message.
Anyway, he came and let us in and was nice. What we liked: the view of the canal, the area, proximity to the vaporetto stop, the cleanliness of the place, and the amenities of an apartment. What I didn't like: the beds are a little uncomfortable, we couldn't get the heat on even though Nicola showed us (we could have called, but were only there for a quick night), and there was no "breakfast" like the site says. However, there was a blow dryer, even though the site says one is not included. Overall, I would recommend this place, but we were also there for one night, so it was mostly just to sleep there. By the way, Venice is amazing! Go there!
