The appartment is really lovely and perfectly located. We spent a week in Sophie's and Florent's place and felt very comfy. We can really recommend it. It is close to everything (great boulangeries, supermarket and Les Halles for the coffee in the morning along some fresh veggies, cheese, fish ...) but also very quite.
Lovely renovated, enough space, great bathroom and the heating is working (we had close to 0 degrees).
