It was a great experience staying there. It is a very stylish and clean space.
We are a group of 4 people and the apartment was perfect for us. Convenience was our biggest concern and its location was amazing - 3 minutes to Arsenale station and 9 minutes to Celestia station (for going to the islands).
If you need a very quiet environment then this apartment is not for you - we could hear people talking on the street until 12am and the water-flowing sound all night long (for the radiator we guess) but we were very tired so we slept very well.
There were ants in the kitchen when we arrived but the staff sent a housekeeper to clean it as soon as we reported it via Whatsapp. We appreciate it so much! Very quick response.
There were lots of utensils and equipment in the kitchen. It was very helpful as we could make some simple breakfast. The bathroom was great too! There was 2-in-1 shampoo/shower gel and a hairdryer.
There were a few things that we didn't expect though. First, we needed to throw the rubbish to the green gabbage ship by ourselves on the last day (which we were told was located at Arsenale but it turned out to be an "out of service ship" so we had to walk all the way to St. Marco!). Second, the hot water was not very stable - if someone was using hot water in the kitchen then there would not be enough hot water for the shower. Third, not all sockets were working - one in the kitchen and one in the living room didn't work. Fourth, it doesn't suit someone with walking difficulty as the stairs are steep and narrow. And the space between the door was very limited that we needed to almost squeeze ourselves to get in the apartment.
All in all, it was still a very positive experience and I would recommend it to friends. It suits people especially like us who are looking for a convenient place that is not too expensive.
