Oscar's place is in a great location, near the Arc de Triomphe, a very cute area. The apartment is cozy and well furnished (though I think they're still working on a few things). It was a bit confusing to find at first but we figured it out. It was a nice cool spot to come back to in the heat of the day. It's also very close to the Ternes metro station, and all the transport near the Arc. The Parc Monceau nearby is a great walk and a chill place to hang out on hot days.
The only complaint I have is that the shower was extremely moldy, including the showerhead. I had to go out and buy cleaning supplies and scrub it myself. This is something that should be very easy to notice and maintain even in a badly ventilated bathroom. Hopefully it can be kept cleaner in the future. I was surprised because everything else seemed tidy.
