Raphael's place was very nice, clean, nicely decorated and big enough for two families with 4 teenagers. The apartment is located in a convenient area in Paris just ten minutes walk from the East train station. There are nice restaurants at walking distance and the convenience of a supermarket (Lidl) right next door. Check-in and check-out was easy and Raphael provided a booklet with very useful information about the area, restaurants, emergency phone numbers etc.
Just a couple of things worth to mention: the apartment has NO windows, so it might feel a bit claustrophobic and it lacks fresh air. Sometimes we had to leave the main door (facing an interior court) open to get some air. Also, the apartment is listed as having TWO (2) bathrooms; however, it has only ONE (1) toilet, which can become a bit challenging depending on how many people stay there.
All and all, it is a very nice place but you should consider the fact that there are no windows and that there is only one toilet for all the guests.
