Location is perfect, 100 m from Champs-Elysées, while the apartment was roomy enough for the two of us. The small balcony is indeed a nice and cute add-on.
Only caveat is that, each morning, from 7.00 to 9.00 am, an army of garbage trucks attack the pile of rubbish digested by Champs-Elysée shopping malls and it can get quite noisy, should you forget to tightly close windows. Luckily enough, the place is air-conditioned and, if only for that, makes it a gem in Paris.
Otherwise, Jonathan is very easy to communicate with and check-in and out processes were super smooth.
All in all, good dig :-)
