Well, to resume, if you can go anywhere else, go for it.
It's a hostel type flat, with a 20 persons capacity, with only one bathroom/toilets (if you're unlucky, in the morning, cold shower)... only one 2 persons table... 4 chairs !! (oohhh, thanks a lot for such accommodations).
The kitchen has the minimum required equipment, one pan, one knife (hope you don't get hungry at the same moment than another guest).
The bedroom, the less worst part, has some space, no lockers, but a furniture for the 4 guest's clothes.
But the mattress !! How can people still using such horrible thing ! Back killers !
I repeat : avoid avoid avoid.
