This apartment is amazing. If you're OK climbing 6 flights of stairs, just book it now! I really can't imagine a better place to stay in Paris. The location is perfect, and you'll both enjoy exploring the neighborhood of Montmartre and easily find public transportation to all the major sights (there are two metro stops within a block of the apartment). The apartment itself is clean, comfortable, full of books and beautiful views. Everything you could need is provided, and I could imagine myself living here so easily. There really are a lot of stairs, so I would not recommend this place for anyone who is not in good shape. But what you pay for in stair climbing, you make up in views. We stayed here for New Year's Eve, and we watched the fireworks over the Arc de Triomphe from the apartment :)
