Whether it is the five minute walk to the Metro, the convenience of Monoprix (supermarket), the outdoor Saturday market, or the shops of Boulogne; this is a great location and will enhance any visit to Paris. You are living like a local, and only ten to fifteen minutes from some of the world's most famous attractions.
Within 24 hours, our teenage sons (12 and 14) felt comfortable in Boulogne, and volunteered to do some of the food shopping. During the week, my 14 year old took the metro by himself.
Thinking about a trip to Paris? I will say - rent this apartment and enjoy every moment.
