We were 9 friends and there were 9 sleeping spots in the house - double and single beds. Be prepared to share the house with a private security officer. He has his own room in the ground floor and is discrete. I forgot his name already.
Breakfast is not fantastic, but suffices to get you going.
Decoration is original and worth seeing.
Overall, the house is value for money and it is recommended for large groups as ours. Bus 14 will take you to and from the city center in about 15 minutes, until 01:30am.
