Even though I didn't get the chance to meet Charles, I met his best friend who was very welcoming and made us feel comfortable. Charles was very nice checking up on us by messages to see if we needed anything.
The apartment is just like in the pictures. Its location is perfect: next to a metro station and a bus stop, you can find everything you need in the neighbourhood. Also, neighbourhood is great and safe. I would definitely recommend this apartment to a couple who wants to stay a few days in Paris.
