The apartment is wonderful, from the location to the cleaningness of the space. We were a group of six friends and we stayed comfortable in this apartments because it's very spacious, both the bedrooms and the living room. The kitchen is a bit small, but it's equipped with everything you need if you want to cook something.
We had no issue with the hot water, we stayed only one night so everyone had to shower that night, but no one had to have a cold shower and, as I said, we were in six. Also the heating system worked just fine, we weren't cold at all during the nigh.
Lastly, the space was sparkling clean, the bathrooms and the bathroom in particular were spotless.
In conclusion, I really recommend stay at this place because it's in the heart of Venice, near almost everything, the host is kind and replied rapidly everytime we needed something and for the price it's practically a bergain (considering the normal prices in Venice for a place this big) .
We will certainly returnin the future.
