The location is perfect so close to all the transportation and stores and coffee shops. Very clean room, staff were friendly and helpful. We stayed in a suite. The air condition worked great and the bedroom was located inside not facing street so was quiet. Free continental breakfast downstairs also was a nice service. We had a very comfortable stay.
