This is a perfect location in the most interesting part of Paris. The apartment itself is well laid out with a spacious bedroom and a well-equipped kitchen. and was spotless when we arrived. Although check-in is automatic, when we needed some advice, Harold responded immediately and was very patient and helpful. We were there during a cool few days in November but the heating soon warmed the apartment and we were very comfortable.
The apartment would not be suitable for anyone with mobility problems, since access is via a short, spiral staircase and, although the bedroom was quiet. the kitchen/lounge area does face a nightclub so anyone very sensitive to noise might find that irritating. For us, it was not an issue at all.
All in all, this is a super place to stay and is highly recommended. We have stayed in many apartments in Paris over many years and this was one of the best.
