The studio is perfectly located: the metro station is very close to it and allows to reach Gare de Lyon in 20 minutes or Champs Elysees in 10 min. You can even visit the Hotel des Invalides by a 5 min walking or the Tour Eiffel after 20 min by foot.
Althoug we had not the chance to know Summer personally, she organised everything in time and, thanks also to her very polite and gentle friend Yang, our arrival occured with no problems.
We absolutely recommend this place!
