The hosts are incredibly nice and willing to help. The location is quite convenient, about 10 mins walk from U Nollendofrplatz or U Kurfurstenstraße.
This condo is on the roof floor and there's no lift so traveler with huge luggages (like me) would sweat a little :P
But once you get in the room and see the view from terrace it's all worth it!
Highly recommended!
