Olivier was incredibly responsive (usually responded in minutes, even though he was on the road/traveling) and provided thorough details about his flat and its amenities and quirks, his expectations of guests and other general information. He was also very well-organized in terms of providing information and in allowing guests to easily access keys. Unfortunately I really only used the apartment to fall asleep for a night so did not really get much use of the apartment, but the roof terrace seems like it would be amazing in good weather - and the place is very well-equipped for sticking around for a long while and sort of making it a temporary home. It's an extremely well-located place, lovely neighborhood, easy access to public transport and offering a lot of options (cafes and restaurants abound) - and yet it offers a quiet and homelike atmosphere.
