This place is awesome! Daniel is a wonderful and very helpful host. Six of us (A dad, mom, 8 y.o. daughter, 10 y.o. daughter, my brother, and my sister in law) stayed there comfortably. Lots of room, upscale appliances and facilities (kitchen, bathroom), and plenty of places to relax and enjoy Paris. Even better is the location. This apartment is on a quiet street (by city standards) that is only 1 block away from a Metro stop. The neighborhood is very cool with lots of nice shops, restaurants, bars, bakeries, and a grocery store. It is also easy to walk down to the Seinne which I highly recommend as you pass through many neat streets. Its also easy to walk the other direction up to the Sacre Coeur. Or, you can head another direction and easily get to the Opera house. I'd recommend eating at Frenchies, Restaurant 52, and Candy bakery.
Daniel is a very good host. His communication was almost instantaneous and he was very helpful with all things Paris.
