No need to search elsewhere: book this studio apartment as it has everything you could want and need!!
In addition, it is in a quiet, safe building in a safe part of the city (Paris is, in general terms, a safe city to begin with). Location is excellent: Metro stop Richelieu-Drouot and Bourse are very close by, and the Roissybus to and from CDG is only a brief walk away as well (behind the Opera). Many key places like the Palais Garnier (Opera), Place Vendome, Louvre, La Madeleine, Department stores, to mention only a few, are also only a short walk away. Host is very responsive to enquiries, apartment is very clean, well-equipped, and check-in process was faultless. Only potential issue is that there is only a (very comfortable) sofa-bed, so the space is perhaps best suited to couples and single travellers. FWIW, I hope to return here on my annual trips to this incredibly beautiful and cultured city.
