Claude an Pierre were nice and welcoming. They provided us with good information regarding trains and getting to certain places.
The location of the flat is great, very close to Javel train station, and 15 min walk to the Eiffel Tower. If you fancy walking, you can pretty much walk to any of the main attractions in Paris from the flat.
Room was nice, with a good view. Bathroom was clean and with a powerful shower. We had a good experience staying there for 8 nights.
