This flat is a very pleasant independent studio within Dagmar's flat. It is very quiet, very clean, not huge but with light, high ceiling and all the necessary features.
Dagmar was very helpful and flexible - thanks again!
(to clarify a point I read in other comments: the ceiling in half of the bathroom is low indeed, I am 6'3 and needed to bend for sure, but NOT in the shower, which has a higher ceiling, and giants can take very pleasant showers (the water is hot and the pression high))
