Tonja was super responsive and very flexible. We added one extra person at the last minute w no problem and were able to drop our bags off early. Though the apt is in a busy area w many restaurants, the apt is in an interior portion of the building facing a courtyard and it was very quiet. There was a “canicule” (heatwave) while we were there and Tonja was kind enough to provide two fans. The apt is not as hot as it could be bc it faces the interior courtyard and there is not direct sun. It’s nicely decorated. Sentier Metro is a minute away and airport is a straight 45 ride from Chatelet. There is a Pain Quotidien at the corner, an Eric Kayser bakery, and Frenchies is less than a 5 min walk. Rue Montorgeuil is super charming street with every choice of food you can imagine, and Les Halles (not charming but convenient) mall is by the Chatelet metro stop 5 min away. Great place!
