The location of the flat was excellent. Looking out the window to the left, we got a view of the Eiffel Tower and the Arc of Triumph. It was near many eateries, and within walking distance from Champs-Elysees. The wifi connection was great, and the beds were comfy. Our hostess was extremely kind and helpful, and communication was really easy. However, since we visited in the summer it often was a little hot because there was no air conditioning, only a small rotating fan. I stayed with my family of four, and it was a bit small, but cozy nonetheless. However, I highly recommend this flat for a party of one or two persons.
P.S. The elevator is quite small (only fits up to three people, or two people and a suitcase), but we thought it was a nice Parisian touch. We loved it, even if two of us had to take the stairs while the other two took the elevator. :)
P.P.S. Be careful of a shelf right outside the bathroom door... My husband bumped his head on the shelf 4 times in one morning. (haha)
