Extreme noise at night when we were there - there is no noise insulation from street. At 2:30am could hear motorcycles and cars hooning. At 3:30am some drunk partygoers were deliberately screaming their heads off just under the window. You will need earplugs. That was only issue.
Need to ring to get buzzed in at checkin so you have to have EU sim. Clean room. Good wifi. Central location.
