I stayed 10 days in Olivier's apartment with my parents and we just loved the experience! Olivier was very helpful, waiting for us and bringing our heavy luggage to the apartment. He also gave good tips about restaurants, shops, public transport and what to do in Paris.
The apartment is very well located, just few steps from the Eiffel Tower, with great restaurants, supermarkets and also a very good boulangerie just next to the building. There are a bus stop and two stations (RER and metro) just few minutes of walk from the apartment.
The apartment looks just the same as the pictures show! The kitchen seems to be small, but is perfect to cook quick meals!
When any of my relatives/friends go to Paris, I will definitely indicate Olivier's apartment!
