The staff was great, very responsive! Our first room had a loud banging with the AC unit so we requested to move rooms. Second room had a very slow draining sink and when the hair dryer was used blew the fuse for the entire room. Also loud trash emptying from building next door starting at 5 am, emptied twice that same morning. Overall the place was clean and well decorated, staff helped where they could and was very nice to interact with. Just disappointed we got the two rooms that had problems.
