Kevin's apartment is really strategic to have a wonderful stay in Paris. It's exactly next to a bus stop and a metro station and one minute far from three other bus stops (one of them takes you exactly under the Eiffel Tower, in Trocadero square). The Louvre is just at the end of the street (maximum 10 minutes walk), around the apartment there are lots of supermarkets, restaurants of all kinds, bakeries and everything you may need. The district of Saint-Germain is one of the richest and safest in Paris, full of nice spots to visit. The house is really well equipped, there's enough space for everything and it is even cleaner and brighter than in the photos.
Kevin is the most kind and helpful host I've ever found on Airbnb, and his apartment will really make you feel at home. Super recommended!
