Lets start with the good things - the price and the location were unbeatable. Right in the middle of historic centre for a price of a hostel, that's greats.
On the other side, the accommodation had too many bad things as well. Firstly, there were ants everywhere in the room, literally hundreds of them. The wall feel extremely thin and you can hear every word of your neighbors, which might be quite noisy as it was in my case, but also from the street. Beside of that, there was no hot water for 3 days, toilet didn't work for last 2 days and some of the other guests were leaving the living room/kitchen really messy (which is not the fault of the host).
Overaly I wouldn't recommend staying.
