We had a pleasant stay at 武夷's place. The studio was nice and clean, comfy bed. It fits 2 people perfectly. It also had all the essentials we needed (microwave, kettle, kitchen utensils, iron). The host also provided bottles of water and milk. Altho, we didn't drink the milk but it was a nice touch. The building was a bit dated, the elevator was quite small only fit 2ppl and 2 luggages. But the people that we met were very friendly and we felt very safe walking around in the neighborhood. There's a supermarket just downstairs and the metro station was a couple mins away which you can get to anywhere in Paris. If you carry some luggages, I would suggest to take taxi/uber to get the studio instead of metro. Most of the metro stations in Paris don't have lift, only stairs.
