Although we did not meet Karim, he was an exceptional host with prompt and good communication. His apartment was great, impeccably clean and a great size for Paris. There were many cafes around the area, with a bar just downstairs that had very good food as well. With 2 metro stations serving the area, it was convenient and the area is nice to walk around. Place de la Republique is just a pleasant 20 minute stroll away. We would definitely stay in Karim's apartment if we return to Paris.
