Very nice location. We stayed with 21 months old baby. It was hard to cary baby and stroller to the third floor but in Paris, in same location we did not expect to have elevetor since the building was historical. We prefered not to have metro and reach everywhere by walk or bus. Paris metro accessibility is reaalyy a pain!
Pierre was always rapid replier. Apartment was clean and it wasn’t noisy during the night although it is a busy location.
