The apartment is a very good size, and is in a pretty unrivalled location if you want to explore the more well-known areas of Venice. The apartment is well equipped, with everything you're likely to need.
My only negative was that during the trip, we arrived back at the apartment, to find the property manager and the owner inside the apartment. The property manager had, on arrival, asked if it would be okay for the owner to visit at 11am the following day. We had planned to be out, so we agreed to this request without much thought. However, finding them there 8 hours later, without a courtesy message, was a little disappointing.
I've still rated 5 stars, as the owner and property manager were very apologetic, and this was the only negative to note during our stay. However, this is something to consider discussing with the property manager prior to, or during, booking.
