My boyfriend and I stayed at Carmen & Mauro's Opera Apartment in early June 2008 and had a wonderful experience.
This was the first time I rented an apartment and was a little apprehensive. However, everything went off "without a hitch." The directions to the apartment were outstanding. Once we arrived, Victoria was there to show us to our room, which looked EXACTLY like the pictures on the website. We received our initial deposit within a week of our return. It was a seamless and hassle-free process.
Two Metro stops are literally a 2- or 3- minute walk away--Opera and Quatre Septembre. Opera is a great metro stop because 3 different metro lines go through here, making access to other parts of the city quick.
My favorite feature of the apartment was the location. Getting from Charles de Galle airport couldn't be simpler--just hop on the Roissybus. Other than a few stops at the other CDG terminals, the only other stop was the Opera (about a 45 minute ride). From there, it was a short 5-minute walk to the apartment.
I also liked that I felt very safe in this neighborhood, which is in the financial district. Most people wore suits. A bank takes up the entire block directly across the street.
Of course, there were tons of restaurants in the area, including many sidewalk cafes along Blvd. des Italiens. A bakery and small grocery/convenience store are literally next door if you need a quick snack to bring back to the apartment.
The bed was very comfortable, and the ceiling fan directly above it kept us cool all night.
Overall, we had a great stay and will stay here again when we return. Please feel free to email me with any questions.
