Nicolas was a great host with a fun property. The apartment was extremely well-located within walking distance from many Paris attractions and close to several metro stations. Restaurants, shops and a grocer were nearby.
The property has an amazing view of the Eiffel Tower so we enjoyed the light show each evening.
The apartment was clean and, while small, everything had a place. Nicolas offered some of his personal items for use as well.
Several things that should be noted. You must walk up four fights of stairs to reach the apartment, and the bathroom is on the first hall as you enter. The rest of the apartment is up a short fight of stairs from the entry/bathroom level. You must duck to enter the apartment level. While the apartment sleeps 5, three of us are 6' tall so it felt a bit small.
Despite the aforementioned, I would recommend Nicolas' apartment for a stay in Paris. Nicolas was a great host and the apartment is very well-located.
