We really enjoyed our stay at Barbara's apartment. We were 2 adults and 2 children, both the bed and the sofa bed (which is huge :-) were very comfortable. We felt the apartment was bigger than it looked in the pictures. There is everything you need in the apartment for a relaxed stay (as we were there for a couple of weeks we really appreciated having a washing machine)-the weather was beautiful for our stay so we really enjoyed having access to an outdoor eating/relaxing space.
The location is great with grocery shops, pharmacies and bakeries/patisseries very near by, very close to two metros (Charonne and Alexandre Dumas) and with a bus stop immediately outside the flat (we used city mapper app which made getting the bus and metro easy), there are also restaurants and takeaways nearby too. We were able to get all over the city very easily. The neighbourhood feels very safe and friendly (even when we got back later around 1am from day trips).
Barbara was a fantastic host-arranging for us to check in late, answering any question straight away.
