We enjoyed our stay at Cedric's place. The place was nice, clean and modern; the location was just under a mile from major sights such as the Opera House and Louvre; and there were many many stores and restaurants near the apartment.
We had a couple of problems which Cedric addressed very quickly.
We had two concerns: There was construction underway next door so if we chose to be in the apartment during work hours, we heard constant, loud noise. Also, the Wifi was very slow at night. I sent pictures via email and 1) I could only send three at a time, and 2) uploading pictures to email was very very slow. I sent about 12 email with pictures attached and it took well over two hours. I did find the wifi to be faster in the morning.
