We had a great stay in Valérie’s apartment. The location is simply phenomenal; it really is in the heart of Paris...you can even see the Centre Pompidou from your window! It's also conveniently located near a major subway station that is a straight shot to CDG airport.
The apartment itself is cozy, with everything you need for a comfortable stay. There are certainly a lot of stairs to climb, but that's free exercise after indulgent French meals! And, as an added benefit, being so high up (not to mention situated on a quaint, small side-street) means your slumber will not be interrupted. Having such intimate and calm quarters in the midst of central Paris is the best of all worlds. I recommend Valérie’s place highly!
