I had a very good experience at Gaelle's place. It was just the right size for myself (or a couple). Gaelle was extremely communicative and helpful. She had the apartment ready for me earlier than check in since I arrived so early to Paris. There is a market right below the apartment which was very convenient and lots of cafes near by to eat. It is a bit far from center of Paris but only about 15-20 euros to get to main attractions. Being in Belleville felt like getting a taste of the real Parisian life, not just the touristy or romantic one. The terrace is very nice too at Gaelle's. I would recommend.
