Myself and family members (five mature adults) had a three night stay in this apartment in May.
Should you want an authentic Parisian experience, then Pierre-Yves's apartment would certainly add to such an experience, it is in an old building and the apartment is tastefully decorated. The bathrooms could do with some updating, but this did not deter from the ambience of the experience. There are local shops, cafes/bars and bakeries within short walking distance from the apartment. Also the metro is within a short walking distance which gave us access to many of the famous landmarks of Paris. We noted that on Tuesday and Thursday mornings there is a food market, with a variety of fresh fruit, cheeses, fish and a bakery.
We thoroughly enjoyed our stay at the apartment and our time in Paris. Whilst I did not meet Pierre-Yves's personally, he was very prompt and informative when replying to my emails and text messages. I would highly recommend this apartment for a Parisian experience.
Thank you Pierre-Yves.
