The appartement is very very well located, modern, well decorated, well equipped, and very clean.
It was perfect for our stay.
Also Ewa and Pau are very nice and reactive, and gave us advices about where to go out when we asked them.
The check in and check out also went perfectly well.
Only one negative point : the stairs to reach the appartement (4th floor) are quite difficult (the staircase is narrow).
