If you choose for a shared room, all is a question of being lucky. If you're, you'll meet nice and respectful people. If you aren't, you'll be disturbed at 3am by people entering "your" room, making useless noise, waking up at 6am and starting to eat breakfast in the room, etc.... So, just try to be lucky;)
Great location, great (and very nice: 'like a family') staff. I stayed there for ten days and I was absolutely happy to have chosen this place: central location + nice staff + clean + cheap.
Nice, cheap, very friendly staff!
Very great youth hostel. Very very cheap... The only problem I experience was the lack of sense of respect from the other girls staying in my room. But that's not due to the hostel (which is not a "party youth hostel")
