It was a really nice stay, thanks very much Nev!
The flat was very clean, comfortable and very close to stores and center.
He actually wasn't there most of the time but it wasn't a problem, he made sure I had everything I needed and asked several times if there is anything missing.
Also if I had questions, I could contact him everytime and he replied fast. There was also a city map and things in my room.
I really enjoyed the stay and can highly recommend it!
