Great host, Kirsten was very quick to respond to any emails, even when she was on holiday!
Apartment is so lovely, in such a great old building, it is decorated very stylishly and was very clean with a well equipped kitchen.
It was very cold while we were in Berlin but the apartment was kept very warm and cosy.
The only comment I'd make is I think it could benefit from having another mirror, apart from the one in the bathroom, but that's just me being picky.
Would very much recommend this place to anyone and I would definitely stay here again.
The bar below is also great and so many lovely restaurants within walking distance too.
