I think the apartment is in a stunning location. The views are breathtaking and so central to everything about Venice. 5 stars for the location.
The 2 faults i would hope the owner can improve is the bedrooms which due to their size and lack of Aircon were too hot to stay in. We all ended up sleeping in the living room sll 3 nights as it was the only one with an AC. This can be fixed by providing AC to both rooms othwise they can be far too hot without ventilation.
The bathroom also the shower is extremely weak in presssure, hope you can fix that.
Otherwise we really enjoyed our stay.
