The apartment is huge and the people in charge are available and easy to reach.
However, the apartment has nothing to do with the pretty pictures. We left the place with all our stuff smelling weird because of the humidity. It took 48 hours to heat the place and the first night was freezing. The first bathroom smelled like an old and neglected public toilet cubicle and to finish I don't understand the price I paid for the cleaning as I found dust about everywhere along with old socks under the bed...
To finish on a positive note (because there are positive aspects to this place, of course!), its position is great, very central, and it is extremely quiet as well as huge.
