"Overall the stay was great. I just wish there were more power outlets in the room. The one by the door was too loose and couldn't be used properly. There was one power strip on the wall but that was it The one thing we didn't like was the smoking room in one corner of the main lobby. Even though it has a door isolating it, the smell of cigarette was still strong around the lobby and reception area."
