Romain's place was great for our 4 night stay in Paris. The location is excellent, you are steps away from the beautiful Buttes Chaumont Park, and very close to Park de Belleville as well.
Romain's place is perfect for a couple on a short stay-medium stay. The apartment is on the top floor, with elevator!!! (Very rare), of a beautiful building in an excellent non-touristy neighborhood. The place is nice and just like it is advertised, but I would say it would be ideal for couples who don't plan to cook too much. The kitchen is nice and equipped, but it is small - authentically Parisian!
For those who love food and wine like me, this location is incredible. The building is attached to a small cheese shop on street level, there is a great Wine Cave across the street, a bakery down the street and lots of good bars in the area. For food, Capitale and Le Cadoret are steps away and fantastic.
Another awesome thing about the location, is you're in the 19th, but you can easily walk to the 20th, 10th or 11th. There are also many easily accessible metro stations, and lime scooters and bikes in the neighbourhood.
