Spartanic, but functional, clean, and in an unbeatable location. I probably wouldn't stay here for a romantic weekend with my SO, but with friends and such, absolutely! However, next time I'd definitely bring earplugs, because the walls are quite thin, and the floorboards and doors have woken us up on more than one occasion when someone was packing for an early flight or coming home drunk from a night out. But no harm done, it says so in the description, after all.
The one thing we actually had to take off a star for was for the fact that the freshly-washed bed linen and towels are being dried in the windowless hallway, so they develop a strong mildew smell over the course of the day, which then wafts into the kitchen area. It seems to be a common practice done every day, not by the other guests but by the cleaning person, so not a single occurence. Mind you, we stayed here in August, when you can open the entrance door to get the air moving a bit, I don't know how the situation might look like during the cold season.
