The apartment is big enough for 5 people (there is only one bathroom but we knew it, so you just have to organize with your friends/family). To my opinion, there is not much noise from outside, but the bunk bed is slightly "squeacky" thus do not choose this bed if you are a sleepwalker! The location is superb, very safe, really 1 minute walk to metro station, and full of shops/restaurants. Marie has been very kind, providing us all that we needed and even more, she gave us useful advices for food and nightlife.
