Good:
Awesome location: Kingston is an great neighborhood with a lot of alternative restaurants and bars. (+ 1 Star)
Privates Rooms: the rooms are good, big and with balcony
Kitchen and breakfast are good. (+ 1 Star)
Bad:
No Air Condition in the rooms and in the bathrooms (- 1 Star)
The bathroom are in very bad conditions, the showers are without light and mold in the corners. (- 2 Stars)
I would recommend this hostel to people how don't care about "bad bathroom" and who loves fancy neighborhoods.
