Frédérique's apartment was in a quiet part of the city, within 10-minute brisk walk to a few different Metro stops that will easily take you to the center of Paris (right to Les Halles or Concorde). The apartment is in a very safe complex (gate + front locked apartment building doors) in a residential neighborhood near Montmartre and Sacre Coeur. The apartment itself was really clean and lovely. Frédérique greeted us herself (we got in fairly late in the evening) and explained everything to us. She was incredibly attentive and checked in with us a few times during our stay to make sure we had everything we needed. The only minor issue was that we didn't end up having any Wi-Fi in the apartment during our stay (she said it was due to a major heat wave that really negatively impacted the city right before we arrived), but she tried to do everything to ameliorate that issue. We didn't get to take much advantage of the beautiful patio due to being out and about during the day and night, but it was an extremely serene and lovely amenity and addition. The bed area had a ceiling fan and there was also a portable floor fan that we used to keep cool while sleeping. Overall, it was a terrific nook in a quiet part of the city, but still provided access to shops, restaurants, and transportation to other areas of the city.
