We stayed in the surfhouse for 2 nights and really enjoyed the good vibes and the great view.
We didn't met Tin, but Zlatan the "housekeeper" made us feel comfortable immediately. The rooms are rather small but the shared kitchen, living room and rooftop are big enough and make it possible to meet the other guests.
We would recommend it to people who like social contact and a nice experience above a comfy and expensive hotel.
