Catherine's apartment is very clean and spacious. It was definitely better than what I was expected. The location is great. It was 2 minutes walk to line 8 metro and ~5 mins walk to line 1 metro. If you arrive via airport, you can take the special airport metro and stop at line 1. Catherine is a great host. She made sure that we had everything that we needed and checked on us to make sure that everything is alright. Highly recommended. Definitely would stay there again when I come back to Paris.
