-Positive-
Host-communicative, responsive, helpful, good to host and to share instructions, talkative, friendly.
Location-ten out of ten. Very close to metro station, grocery store, pharmacy, restaurants, bakeries...
-Negative-
No door knob neither lock.
Cleanliness, too much mold and peeling paint on the walls
In general I had a very good stay, however this place is more recommend to backpackers or students. If you are a professional in late twenties or thirties book something else.
