My wife and I spent a week at Daphne’s apartment and had the best time! The location is close to a few different metro stops including Gare de l’Est, which hooks up with a number of lines to get you around the city. The Canal St. Martin is close by and offers a nice, scenic walking route as well, with neighborhood cafes and restaurants worth checking out.
The apartment felt light and airy and had all the amenities that we needed to make our stay comfortable in Paris (including a washing machine). There was plenty of space for the two of us to stretch out and settle in without feeling confined to a small space.
