A too short stay in such a lovely place!
Joachim is an excellent host, very helpful and easygoing. And his flat is so cosy, accurate in every detail, equipped with all you may need, very clean and quiet, though situated in a lively neighbourhood. From there, you can just start walking around and looking around, ready to amazement, soon immersed in the magical Parisian atmosphere, or easily reach the public transport, very close to the apartment, to move through the city.
Will be back as soon as possible. Highly recommended!
