We had a fantastic stay at William's apartment. Check-in was a breeze. The location is fantastic and probably the best part of William's place. We walked to almost everything we wanted to do and see in Paris (Museum D'Orsay, Pompidou, Picasso Museum, 11e restaurants, etc.) When we wanted to take the metro, we were only steps from that as well. A lot of fun wine bars, bistros, and cafes in the streets surrounding the apartment too.
In terms of the apartment, it is a very nice, relaxing spot. Very comfortable bed. Nice shower. Great coffee machine. Overall, it's a great place to call your home while you explore all that Paris has to offer.
