The apartment was pretty nice and gives off a vibe of an old country house.
The location was very good: a bit outside of the main touristy areas but still within 5-10 minutes walk of everything important. We enjoyed being able to grab a ferry to the beach and murano/burano. If you are staying during the warm season don't forget the sunscreen. The sun is brutal there.
Regarding sleeping there are kids and main bedroom and the main bed is pretty big. It's dead quiet so we could rest very well. The aircon really saves the day, especially because there are some mosquitoes flying about in the evenings.
The kitchen is very big and well equipped. There is a very big fridge and dishwasher, lots of pots, pans and utensils. We had most of our meals at home, there is a pretty good grocery store nearby with very delicious fresh fish. There are also a lot of restaurants along the street taking you to the city center.
If you want to watch some movies or do some work: the internet was an extremely fast fiber optic connection.
The only downside was a little bit of mold growing in the bathroom. The rest of the apartment was very clean and I'm sure the bathroom will be cleaned up in due time as well.
Overall we enjoyed our stay a lot, got a nice tan and had a lot of fun in the city!
