Very, very poor wi-fi. On that particular night, poor water pressure, but even I was under the impression that that was exception and not a rule.
Not being able to connect to internet was totally forgiven and forgotten when we realized how welcoming and helpful the stuff of this hotel is. First of all, location (Mestre) was perfect for us, considering that we wanted to visit Venice on the next day. Second, they let us we leave our car at the hotel parking (even after we checked out, free of charge!) and hotel arranged transportation (by their car) to Venice and also picked us up when we were done sightseeing for more than reasonable price. They also arranged tickets for Venice water bus. Incredibly nice of them and made it easy, relaxing and efficient to see good deal of Venice in such a short time. Also, even if the hotel is practically few meters away from the rails, I must say isolation is perfect - you can tell only after you see through the window.
