The manager was polite and made check-in easy.
Be prepared to pay $$$ for a private water taxi to make life easier.
As the apartment was on the ground floor, it was dark. Very old dated decor and the sofa chairs are very uncomfortable. We stayed there for 2 nights and it was enough.
It was reasonably clean and probably a good option if you had a young family - but only for a night or two - which is perhaps enough for Venice anyway. Probably just under a 3 star rating in my opinion but would be much better than hotels that give themselves 3 stars.
