Cheapsleep is a good hostel to sleep, and good cause you're really close from stop point for bus and tramway for city center and airport.
After that inside, the hostel is not really clean, the living room is really really simple, the kitchen was not clean everytime, and bathroom and toilets were not cleaned every days and not nice cause the hostel is busy. And during the weekend, the nights were really noisy!
A good hostel if you don't care about all those details, if you do, it's maybe not the best one ..
