This is a very basic, private room in a hotel-like place in a very good location at a very affordable price. I would definitely come again, but don't expect anything beyond a bed, a place to hang up your clothes, a TV, and shared bathrooms/shower.
The reason I'm giving this place 4 stars instead of 5 is that the whole experience is completely devoid of any human connection. Call me old-fashioned, but BnB, even with the Air in front of it, implies to me that you are staying at someone's place. You might not necessarily meet this person (which is too bad), but at least the place radiates some kind of personality. This, however, is essentially a boarding house. Again, for the price and location, it's a fine boarding house, but the concept robs the spirit of private accommodation. I'm not sure AirBnB is the kind of site where this place should be advertised.
