Sarah and Dimitri's apartment is the perfect Airbnb experience - up 'sur les toits de Paris' in the lively and interesting Marais district it allows you to become a Parisian for a little while. The apartment is compact, comfortable and absolutely charming, with a well equipped kitchen, great bathroom and shower room... everything you need. There is a delightful balcony from which to watch the street-life below, and with - if you stretch a little - a view of Notre Dame! Looking at the many books, CDs and trinkets, we felt that we would really have liked to get to know the owners... but they were out of town and we didn't have the chance. The organisation for picking up the key was perfect and the instructions left were clear. We walked almost everywhere and the Centre Pompidou is just one block away (you can glimpse the roof from the bedroom windows). Despite being in the centre of the Marais area, the flat is marvellously quiet (at least in the chill of winter, when we visited). The only possible drawbacks - neither of which bothered us much - are the 5 flights of steep narrow steps leading up to the 5th floor (excellent for the leg muscles!) and the rather firm tatami mat and futon double bed, which may not suit those wishing for a softer place to sleep.
Overall, we highly recommend this apartment as a wonderful, memorable place from which to venture out into Paris!
