Olivier was a great host! Very helpful and nice, even when we arrived later than expected to the apartment. The place is a perfect little studio, very compact, with anything you might need for a short stay. It's about a five storey walk-up. The neighborhood around it has many African shops, and is very lively; there were outdoor concerts to go to at night in the surrounding streets, which was lots of fun. There's a bike station just outside the building, and it's a short walk from the metro.
