Olivier’s flat is great for a family or friends trip. We were 5 and we were quite comfortable there. The common area is very big so we could hang out and eat there without feeling too packed. We had all we needed to cook and wash some clothes.
Since it was winter we didn’t really use the balcony but it looked great out there.
The area is alright. The metro station is really close and there are several shops nearby. It’s relatively close from the train stations north and east and you can get to the main spots within 35 minutes by metro more or less. It’s great for some proper tourism. Olivier was also quite flexible with our check-in and check-out. Really recommend it.
