I stayed with my partner at Cay's for 3 nights and everything was perfect, the flat was very neat and had an amazing atmosphere. It's in a quiet neighborhood with supermarkets, pharmacy and tram stop nearby. The center is about 40 mins away by S Bahn.
Cay let us use her towels, wifi, kitchen equipment, etc and she was very accomodating and accessible through text. We didn't get to meet but I'm sure she's a lovely person in real life.
This was an amazing find for its price and we'd be lucky to visit again. Thank you for letting us stay at your place.
