Staying in Rita's apartment has been perfect for me. The location is super convenient -- it's right by two train lines, and also a pretty quick walk to St Lazare where you can catch several more. I love the Batignolles (the neighborhood). The apartment itself is a great size for one person or a couple. Has everything you need, and Rita is super accessible if you have any questions. It's a great option for a stay in Paris if you don't want to be in one of the more touristy locations.
