There is no reception at night and there's no key either for the hostel or the rooms. All remains open! The only security they are providing is a door code for the building entrance, easy to copy if you check people entering, or if you just come in after somebody else.
The air conditioning stopped working at night, dropping water to the floor of the room. There was nobody at reception to make aware of it.
It is kind of party hostel, as nobody is there to tell party guests to keep quiet. I did and they laugh at me (it was 1 AM and they were still talking too loud in the kitchen). The hostel could do something if they were at least there.
It is very central, but that means a lot of noise until late on the streets, and also from 5 AM is loud outside, as they are setting up the market.
I do not recomend this hostel. Lockers in the rooms were tiny and easy to open, so security is a big FAIL.
