All in all the apartment is cozy and ideal for travellers who prefer to use public transport. The underground lines are literally just around the corner. However, this location also means that there is lots of traffic so it can be a bit noisy sometimes. But the windows are modern and fairly soundproof, so with the windows shut it's okay.
The studio is simple but clean and perfectly alright for one or two people.
I enjoyed my stay and would recommend Patrick's and Franck's apartment.
