It is a nice and quiet hotel in Murano Island. You should be aware that Murano closes very early - especially during the week. It is absolutely dead after 6pm but lively during day with many day tourists coming to look at glass art, which Murano is known for.
When I arrive they gave me the wrong room - a single, whereas I had booked a double. They did the best they could to solve the issue. I had a very nice room except for the last night where I had to change to another and not very nice room. You should avoid having the room next to the reception, where you will hear the bell from the door every thime someone enters.
The staff are friendly and will do their best to make it a comfortable stay.
As others have noted: the check out time is 10.30am, not 11am. In the listing it looks like breakfast is included, but it is not included, though I had breakfast without extra pay, but maybe to make up for the inconvenience and confusion about the room and changing of room.
