I had a wonderful time at Olga and Jean's place. I had a conference at Paris Expo/Porte de Versailles, and this studio was very conveniently located for that, about a 10 minute walk away. And with the Metro stop nearby, it was also easy to get into the city center, about 30 mins. As for the studio itself, it is nice and clean and the system with raising or lowering the bed makes very efficient use of the space available. Olga met me for check-in and check-out, was on time for both, was very understanding and accommodating despite my delay arriving into Paris and was easily accessible for any questions I had.
