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.

4/10 Fair

Older hotel with limited facilities. Reception tiny and cluttered, not at all welcoming. No air conditioning, breakfast poor - no bread, very basic items. Very small breakfast room. Only appeal location. Given the charge per night of USD25 for ‘extras’ very disappointing. Would not recommend except perhaps for a one night stay.

Room was spotless. Antonio went above and beyond when we needed a second room. When my phone wouldn’t work to book a tour online, the front desk staff were courteous and let me borrow the use of the hotel computer for 2 minutes to book the tour. You saved our vacation.
