My mom and I had a great stay at Rodolphe`s. The apartment has basic amenities, so don't expect to be cooking four course meals, but the hot plates and convection oven were more than adequate to make eggs for breakfast and heat up goodies from Picard. The bed was comfy and the bedroom on the larger side, and if the weather's nice, the balcony is an idyllic place to take a coffee or cocktail. The building would be a bit difficult to access for anyone with mobility issues - even though there is an elevator, there are quite a few stairs getting into the building. The neighborhood is authentic and not very touristy, so if it's your first time in Paris and/or you plan to visit a lot of the tourist destinations, you'll have to take the subway (which is very close!) quite a bit. If you're looking for a neighborhood experience, there are several great markets within walking distance, as well as grocery stores, bakeries, cafes, brasseries, and nice jogging routes.
Rodolphe was generally helpful and checked in on us via WhatsApp several times during our stay to make sure we had everything we needed. Very good experience.
