Advantages:
The apartment is well located, near the historic center. The apartment is spacious and the living room and kitchen very bright. It was really comfortable.
Downside:
Almost impossible to open the windows: the living room overlooking a street under construction, there was noise and smells of building sites, and the side of the bedroom overlooking a narrow courtyard, smells of fries were coming up almost all day and night... sometimes till 3 am.
The elevator was unusable because it was systematically blocked. The apartment beeing on the fourth floor, it was not practical for getting up and down suitcases.
Aside from these disadvantages, it's a really nice and pleasant appartement.
