We booked this hotel for a weekend in family. As we have 2 young kids, we asked for a suite.
From reception to check out, almost everything was simply excellent. The staff is great, they all speak english and are helpful and polite. The room was stunning, heavily decorated but that's Venice style so no complain here. It was really clean, made twice a day, and everything worked as expected. Our suite was facing the back yard and the view was really lovely.
The only disappointing thing was the room service. It took around 30min to come (which is ok), it is very pricey (but hey, this is a 4 star hotel in Venice), but the quality was just not there... We ordered a cheeseburger (20 euros...) and a pizza margarita. Both were far below expectations, probably just frozen food heated up on order. So although we had to put the kids to bed early we made sure to eat out on the second night.
Overall, it was a very nice experience and we definitely recommend this hotel.
