we had a great time in Paris, and the studio made our stay much more comfortable than staying at a hotel. Stephanie is very organized and friendly. The studio is fully equipped, with high speed internet, a phone, big screen TV, washer and dryer, and all the kitchen appliances you would need to make a small meal.
Whats best about this apartment is its location. It's very close to the Arc de Triumph, which means its walking distance (if you enjoy a good walk) from the Louvre and other great locations. It's also right by the metro station. We loved being so close to everything.

stephanie's studio is perfect for two people. we used the futon which was very comfortable. you may find the mattress above the stairs to not be spacious enough. Also though I was comfortable in the room, my husband who's 6'2'' had a hard time fitting in the shower, and moving around in the kitchen. the space is small, but that is typical it seems in paris.

Also know that the apartment is several stories up, and upi might not want bring more than one piece of luggage, and keep it light!
