This was my second hostel to stay at in Budapest and it was sub par. It's fine if you just want to sleep there but the atmosphere was a little depressing. There also aren't any lockers to lock up your bags, which just puts that small thought in the back of your mind that maybe something will happen to your bag. It's not horrible but you can find something a lot better in Budapest for around the same price.
Best hostel I've stayed at hands down in Europe. I wish more hostels were like Big Fish.
