My friends and I had a great time at Marie and Simon's apartment. The apartment was warm, cozy, clean, and comfortable. There is just about enough room for four people since there are 2 beds. They weren't there to give us the keys but they had a kind friend drop it off and also wrote us notes in case we needed anything. They even bought us a bit of food and milk.
The apartment is very close to the metro stop (about a minute) and there are great restaurants in the area, and even though the neighborhood can be busy at night, the noise doesn't get into the apartment. Overall, my friends and I had a great time traveling while on a budget and would recommend the apartment.
