We had a great stay in Marvin's studio. The studio itself was in a good location, short walk from a number of metro stations, and not far from the Eiffel Tower and Champ de Mars, with a lot of the other attractions a slightly longer walk away (but definitely still walkable). The studio is also at the back/middle of the building so no street noise and very quiet through the night which was great. Good amount of space for 2 people, with good facilities to cook/prepare food if you wanted to. Marvin was very helpful and great at communicating. We would definitely recommend staying here.
