We stayed there for 2 nights over new year's eve. It's possible to sleep there with 4 people, because the couch gives a fair amount of space. I recommend renting a garage/parking space in advance, finding a parking lot on the streets is nearly impossible. We don't really have major complaints, the only thing is, that the dishes weren't really clean and we noticed, that the dishwasher doesn't do its job properly, so you may be better with washing them yourselves.
