Olaf's place is an ideal place if you love a pretty and peaceful neighborhood and a friendly and hospitable host. The room and common space is very nice with lots of space and sunshine. The thing I appreciate most is we had a key of the house and the room so we can leave and come back anytime we want without bothering anyone.
It's not near the center but you can walk 12m to the tram and about another 40m by train to the center.
Overall a very nice experience, thank you Olaf!
