Great place for an overnight stay. We were two couples and the flat was very clean and accommodating. 1 private bedroom and one couch that combines to make a second bed in the living area.
Only drawback is the single bathroom is accessed through the bedroom so expect to sleep with the door open and your mates walking through your room at night. As we are friends and family this did not bother us. Your expectations may vary however. Also the bathroom is small and lacks the counter space some girls may need for their getting-ready-routines.
All in all, none of these shortcomings bothered us and we had a great one-night stay. Any longer and things may have gotten cramped.
Friendly hosts and check in was simple and straight forward.
Would recommend for any couple or small group of close friends.
