I agree with the other review: the photos are flatering.
Pros:
-The flat is well located.
-Ulric answered my mails very quickly.
-The apartment has everything you'd need.
Cons:
-The neighborhood looks dangerous (in fact, I read somewhere else that 'the neighborhood is not as dangerous as everybody says, as long as you don't visit it in the night'), and the streets are really dirty.
-When I went out in the night, I was worried because there was always suspicious people near the door.
-The internet is REALLY SLOW, because it is connected to the cellular network, and there's NOTHING to do about it.
-The sofa bed in the lower floor is not very comfortable.
-I had to wait for half an hour before going to the apartment, even when I announced the time of my arrival two days before.

Conclusion: Good location, well equipped, suspicious-looking neighborhood, slow internet (almost impossible to communicate).
