My stay in AB Apartment was wonderful, the apartment was very clean, complete in furnitures and amenities.
Everthing was fine? Yes but ...
There are only 2 bad points:
1) no pillow choice (mine was very low)
2) street windows very old and it was impossible to close them completely. This is a problem for the noise (there is a bar below) and for the cold. I was here in summer so I had no problems but in winter it is a big problem.
