Great location right next to the Pantheon, and somewhat close to RER and Metro stations. It was very queit at night. Although we were not expecting the couch in the photos to also be the bed, it was no issue because it was surprisingly comfortable and easy to sleep on.
Check in was a minor inconvenience when you are coming from the airport with luggage, as you have to go to a Keycafe first, ane then walk to the apartment.
