This unit is right in the heart of Champs-Elysees, which comes with both pros and cons. The location is very convenient to both central sites and public transit. We used this to get to Roland Garros for the French Open which was perfect. Although a bit small, the apartment was clean and neat and will serve basic needs.
It should be noted that the unit does NOT have A/C, which means if you stay during the summer you will almost certainly have to have the window open. This presents problems during weekend evenings as the neighbors can be LOUD. We had a neighbor in a nearby unit in the courtyard playing music until 5AM on the night of our departure, which made sleep very difficult considering we had to have the window open to keep the unit cool enough for sleep. We also had to sleep on the futon instead of the loft due to the temperature.
The unit could be improved by installing a wall-mounted A/C. Otherwise, we would not recommend for summer travelers.
