Zelkja is a wonderful host, friendly and very helpful.
The apartment is in a great location, very close to 2 metro stops and just up the road from Bastille. There are great local restaurants, Monsoir and Vertigo in particular. The apartment is small but that's to be expected in Paris. The apartment itself appears old and can be a little stuffy, with thin walls. However, Zelkja has done a great job in turning the space into somewhere enjoyable to stay to get a true Parisian experience.
