I stayed at Kristin's apt for two nights and overall had a mildly negative experience: I guess it depends a lot on your taste and wether or not you like staying in a basement (which could be considered cosy or slightly unnerving/creepy, depending on how much you like the dwarfs mural paintings ;)
Positive stuff: it's pretty big, good shower - great water pressure, there are magazines, board games and a piano (!)
Mildly negative stuff: there's not a lot of intimacy (it's one big room, the bed are separated mainly with curtains), the decoration is quirky and a bit old-fashioned, lack of natural light (basement-style place)-overall not a very welcoming atmosphere.
The place is in a nice, safe neighborhood, although not very central.
