It's about a 30 euro taxi ride from Orly airport to this place (or you could take the metro train). After the taxi driver dropped us off, I saw a restaurant, a store, and a door in between the two. After inputting the code to open the door, we were in a small hallway. Per René's instructions, I went up a flight of stairs and the first door I saw was the door to the apartment. I put the code into the lockbox, took out the key, and opened the narrow door into the apartment.
The apartment is a nice cozy studio apartment. It's clean and it looks well taken care of. René has a great guestbook with instructions on the apartment itself, and instructions how to get around town. It even has a washing machine with instructions of course. When you look out of the window, you can see the street below you with all of the shops and restaurants. On the other side of the clothing store is the Main Street and the metro station not too far away either. René had a few umbrellas for us which really came in handy as it rained a couple of days. It's a great convenient location and I'm sure anyone would be satisfied with their stay here. I would definitely stay here again.
