My wife and I stayed in the flat for four nights and were absolutely satisfied with it as well as with the service.
We arrived at 1am as our flight was estimated and Wilken kindly met us to give the keys and show the flat. The condition of the apartment was exactly as described and it was in extremely clean state. We really enjoyed using modern shower and fully equipped kitchen during our stay.
The apartment has very convenient location, lots of nice cafés nearby and there is Sant Antoni market literally around the corner, where we shopped for freshest food every day.
Highly recommend this comfortable and quiet place.
