The apartment is great: it has a perfect location - practically everything can be reached by feet; it is in an authentic Haussmann building, you feel like a real citizen. If you arrive in CDG, there is a Roissybus with the end stop at the Opera, 5 min walk from the app-t. Communication was very quick and nice. I would also like to admit easy check-out w/o any waiting. The only disappointing moment throughout the stay was that the apartment was not perfectly clean, especially the floors and surfaces. The bedsheets were not perfectly fresh. Though I was reassured that they were cleaned in a laundry, that was obviously done in a poor way: it had a disturbing smell. We had to use spare bedsheets that seemed to be cleaner. In general, I was glad to stay in the apartment and after some improvements concerning cleanness can recommend it for a stay.
