We had a wonderful time in this sunny penthouse apartment. Nadia was helpful and responsive to all my questions, both before our trip and once we were in Paris. The apartment is very nicely equipped and charmingly decorated, with plenty of personal touches that would not be possible in a hotel. The light filled greenhouse-like dining room made the perfect place to enjoy breakfast, and plan our day, while watching the clouds come and go overhead. The kitchen is small but filled with anything you might need to make a meal and it comes equipped with a nifty European clothes washer/dryer - that, once you align the dial properly, both washes and drys your clothes in a single appliance. The bedrooms were comfortable and quiet. While the bath was very nice, all lined in marble, with a separate loo for the toilet and an additional tiny sink, this came in quite handy since there were five adults in our group.
The one drawback was the sofa bed, which is not comfortable as a bed or as a sofa - it's too soft seat cushions unfold to make a very soft bed mattress directly on the (hard) floor. There is a sort plank across the front the sofa at the floor level that made it quite uncomfortable to sleep with your head towards the back of the sofa, sleeping with your head at the foot of this "bed" was better, but not great.
Otherwise the salon was a really pleasant room, filled with books and magazines, as well as a TV - where we gathered each evening to discuss our options for the next day.
We did have one glitch in that the toilet started to leak after a few days, but this problem was handled in the nicest way - when I e-mailed Nadia to let her know there was a problem she put me in direct touch with Jeanne, the owner (they were both out of town at the time) who arranged for a plumber to come at my convenience to fix this as quickly as possible. A little touch of real life that barely made a dent in our short sejour.
Though the location is not central the surrounding neighborhood is typically Parisian, Haussmanian buildings with mansard roofs and plenty of services (I defy you to walk past the corner bakery without buying something) not to mention a magnificent fountain in the round-point by the Metro stop. There was also a street market on certain days. And then the two lines of the Metro will get you to all the places you want to see. All this made it easy to imagine we were really living in Paris for a (too) short time!
