We generally enjoyed our time in the apartment. The location was fantastic and enabled us to get to all parts of Venice relatively easily and quickly. As a base for a few days of exploring the location is hard to beat.
That said, there were a few things that counted against it:
1. Loads of stairs. It is high up and steep! Once you get down you aren't that keen on coming. Ack up any time soon and vice versa.
2. Mosquitos. It was unusually warm for this time of year and the mossies were BAD. This wouldn't have been an issue if the nets on the windows worked but they didn't. Rather frustratingly, when we told the managing agents about the broken nets, they said they were aware but hadn't actually told us.
3. Shower door was broken. We notified the managing agents and again the issue was not that they didn't know but that they hadn't told us on arrival.
4. Beds and pillows. The beds weren't that comfortable but were ok however the pillows were limp and pointless.
that aside, I think we would stay there again.
