My boyfriend and I just got back from staying two nights at this lovely B&B in Venice. We were put into the "purple room" on the 3rd floor, and it was absolutely perfect for a romantic weekend getaway. The decor is, according to my boyfriend, 18th Century Bordello Glam. :-) Anthony (owner? manager? I didn't get his title) was very nice and very well informed about the area. He recommended great places serving gelato (Nico's) and pizza (Ae Oche) and we had the most perfect meal at A Beccafico, which is right on the square.
As others have noted, there is no lift, so be prepared to walk up some stairs. Also, you check in at the sister hotel Laconda Fiorita and you will be escorted over across the square to Bloom. The place itself is very easy to find using the directions on the website. We purchased the Alilaguna water bus service to and from the airport and it's a quick walk from the San Angelo stop to the hotel itself.
We'll definitely stay here again!
