We had a nice stay at Sofia's place. The apartment is very well located, just a few minutes from Porte d'Italie, where there's a metro station and plenty of buses. There are also several supermarkets close by. With 10 minutes on foot, you're in the Asian district, with lots of Vietnamese and other Asian restaurants. We'd also recommend exploring the Butte aux Cailles, a nice neighbourhood where there several nice restaurants and bars. The apartment is roomy, with a large living room area and a big bathroom. The communication with Sofia was fine. We had some delays on our way to Paris and we were lucky to have her brother hand over the keys outside the standard check-in hours.
