8.6/10 Excellent! (1,002 reviews)
Good location, boutique hotel. The bathroom is pretty small and it is hard to put your toothbrushes there. It is an old hotel, so the rooms have vintage feel, which comes with fewer amenities. There is no parking, but the valet is available and decently priced, just make sure that you order your car well ahead, if you need it.
