This hotel is actually a 4th-floor apartment unit that has been converted into individual rooms for rent. There is no exterior sign for the hotel, but it appears to be legitimate and fully licensed by the local government. The top-floor/attic rooms seem to be newly constructed additions to the original apartment.
The room was clean and the bathroom fixtures were brand new. We didn't use the shower since we were only there for a quick nap for a few hours before moving to our primary hotel. Because we arrived early in the morning and our main hotel couldn't accommodate an early check-in, we ended up booking a full day here just to sleep.
Tips for future guests:
Call Ahead: It is highly recommended to call the manager ahead of time if you are arriving early in the morning, as the front desk is only staffed after 9:00 AM.
Check-In: Call her again when you are close to the building, and she will meet you downstairs within a few minutes to guide you upstairs.
Luggage & Stairs: The building has an elevator to the 4th floor. However, if you are assigned a top-floor/attic room (effectively on the 5th floor), you will need to carry your luggage up a very narrow flight of stairs or leave it at the front desk area.
