Outstanding location one block from the Les Halles Forum train station. You can take the RER B train direct from Charles de Guaille without transfer and simply walk to the apartment. Great views from rooftop deck. Decor is interesting and a bit worn but very comfortable. The only negatives are the six story walk up and no air conditioning. We visited during the July 2019 heat wave and a few evenings were very hot. Everything else was great.
