This flat is very, very noisy ! Neighbors had a party practically every night, you can hear the street from the room (because windows isolation is practically inexistant), and above all, you can hear everything that's happening in the building's corridor and stairs since the windows of the room & bathroom looks directly into it (yes, it's very strange, you open them and you're literally in the building's corridor).
Also, communication with the company is very difficult, they take a very long time to answer and are not helpful even if they say they are. They give you false information and keep justifying themselves. I'm pretty sure they will respond to this comment by justifying themselves like they did with every other comment. All I did was complaining because of the noise and asked to leave earlier, which they agreed, and finally refused to reimburse for the nights I didn't spend there, after I left. It's just not people you can trust and can be happy to give money to, they'll do everything in their own interest without any consideration for their guest's satisfaction.
Apart from that, the flat is quite nice and perfectly located, its equipments are very functional, and arrival was smooth. I would totally recommend if it was not so noisy, and run by people that are so unconcerned by customer satisfaction.
