We truly enjoyed our stay at Charlotte's apartment.
Pros: it was clean, comfortable and spacious; the kitchen was well-equipped.
The location is great: it's close to three different metro lines that will get you everywhere around the city. Lively neighborhood with many options for eating/drinking.
Our communication with Charlotte was smooth, she responded very quickly to our messages and she provided all necessary information :)
Cons: even though it's a safe neighborhood, there was some sketchy guy outside the building at all times; we didn't bother them and they didn't even take a second look at us, but it still felt a bit strange.
Also, the apartment was a bit cold at night, but it was due to the fact that the central heating wasn't on in September (Charlotte informed us that it's turned on as of October).
All in all, we had a great stay and we would certainly choose Charlotte's place again!
