We booked Ottos house to meet up with family and friends. We were quite many and the house was big enough to host 8 people. Everything went smooth, the house was clean and check-in was convenient. I don't know if there really is space for 12 people as it says in the announcement but for 8 people it definitely was appropriate! I can recommend Otto as a host and his place to anyone wanting to visit Stockholm and looking for a spacious accommodation.
