Stayed here for the last two nights of our honeymoon; selected this hotel based on location close to train station as well as a waterbus stop for a morning airport transfer on our way out of Italy. It is a bit far from the main tourist attractions at Rialto, Saint Mark's, etc, but a convenient waterbus stop on the Grand Canal is about 10 minutes walk away -- and this means the location is nice and quiet at night, but still near to shops/restaurants. We also booked with airline points, another reason that drove us here.
Clean room and bathroom. Room was tight, but we each only had one carry-on suitcase. Bed a little hard, most people would probably want an extra pillow as well. Showering was a new experience with handheld shower head and no curtain/divider to speak of -- almost easier to just take a bath!
Wi-fi was spotty throughout the stay. Worked fine when connected but often dropped, and then would have trouble reconnecting.
Pleasant interactions with all staff. You must leave the key to your room with reception each time you leave; receptions is manned 24 hours. At first I thought this was strange, but eventually enjoyed it as I never worried about losing the key.
