The lack of a laundry may seem inconvenient at first, but as there is a (public) laundry about a minutes walk away, this really isn't much of a problem. Kitchen is well stocked with cutlery, etc, showers are kept clean, common room is nice to relax, and the computer actually works, unlike in many hostels I've stayed in (bonus points for the doge wallpaper)
Aside from things it would be unfair to blame on the hostel (My God, the two guys opposite me could snore in the Olympics), I enjoyed my brief stay here. The facilities were ok (one shower door was broken, but it otherwise worked), although having the facilities spread over two buildings was a little confusing. Helpful staff, kept clean, overall good place.
You share the bathroom and shower, much like in any other hostel, but the fact your bedroom is private makes this probably the best you could ever expect for £20.
