Good, easy, clear communication and quickly reachable when a small problem occured.
Perfect location very close to the city, the airport and anything one could want.
Clean sheets and bed and lovely rooftop terrace to share with the other guests (we never met anyone else there thought).
Just beware that the staircase is quite narrow if you have physical problems it might be a challenge. But if you're young/ fit it won't be a problem
The bathroom was quite moldy but otherwise clean.
In general we really enjoyed our stay at the appartment and loved it most for its location and roof terrace!
