Charlie's apartment was the perfect place to stay for a long weekend in Paris. The place is very, very, very small and it requires a long walk up several flights of very outdated stairs. It's definitely not a good place to stay with someone you don't know very well or if you aren't physically capable of walking up stairs (maybe 7 flights?) several times a day. But Charlie was excellently prompt when it came to answering emails and the small space was just what we needed. The shared bathroom is down the hallway, but I never once saw anyone else walking to or from it. The apartment and the bathroom were very clean, as well. The room is very modern even though the building and the stairs are very old. Stay here if you're just looking for a nice place to crash and will mostly be out exploring Paris. It's also in a great location, just a few seconds away from the Cadet metro station. There are also markets, restaurants and a Starbucks right outside. I definitely recommend Charlie's flat!
