Our stay at Clara's apartment was really great. It is conveniently located in a lovely neighbourhood very close to the canal St. Martin and a couple of metro stations. There is a really wonderful bakery "Du pain et des idees" where we got our breakfast on weekdays just around the corner. Lots of restaurants on the same street and in the neighbourhood, as well as supermarkets and shops.
The apartment is on the top floor (5th) and you have to go up the stairs, which gives a good exercise... but it's a typical Paris apartment building and it's really lovely. The apartment is clean and comfortable.
We walked around in the neighbourhood a lot, enjoying traditionally popular neighbourhood of Belleville, Ménilmontant and Oberkampf, and had a wonderful stay.
