Alice was a great host: she met us at the apartment and gave us a tour when we arrived, and left us a booklet filled with recommendations. The apartment is stylish – exactly as you see in the photos. The only thing to note is that the mezzanine (where the bedroom is) is accessed by ladder and has a low ceiling, so you have to crawl from the ladder into bed – it might be an issue for some people, but it didn't bother us too much and the bed was very comfortable. The apartment was also quiet, and there are supermarkets, cafes etc just round the corner.
The local area is great, and it's really easy to get around by foot (which was what we did most of the time), Metro (it took us about 25 mins from Gare du Nord to the apartment) or taxi (only about 10-15 mins in an Uber). My friends and I really enjoyed our stay in Alice's apartment!
