The apartment is fine and suitable for 12 persons. You should consider that some of the sleeping accommodations are pretty basic but it is fine for a group of young people. Self check-in is simple and worked without any problems. There is a guarded parking lot 5 minutes away. Only thing i have to note is that the kitchen misses basic equipment! There are only plates, cutlery, glasses and a pot available. If you need it, bring coffee filters, dish liquid and stuff like this with you!
