We spent three nights at Natacha and Thierry's place. Our experience there was excellent: the room is warm and comfortable, the bathroom has everything you need and the breakfast was unbeatable. We didn't see Natacha that much, but Thierry is super nice. The apartment is located in a very quiet area, but with easy and quick access to most of Paris' attractions. Their cats are lovely too, although they might be a little bit too friendly for someone with severe allergies. Anyway, that wasn't our case.
Overall, we had an excellent time in their place and we'd love to be back if they have us.
