The stay was great and Blaire is a very kind host!
We had no problem with communication and arrival. The apartment is located very conveniently: close to the city centre and u-Bahn, Kreuzberg's pubs and restaurants. There is also a city bike station nearby (totally recommend taking a bike when visiting Berlin!)
The room and bathroom were clean, though a little bit messy. Blaire added some snacks and even a UV sanitizer because of the pandemic, which was very thoughtful.
I would definitely come back :)
