We spent 5 nights at Rue Cremieux 15. The studio is located a few minutes walk from Gare de Lyon railway station where you can get straight from CDG airport by Line 4 shuttle service. As mentioned by many raters the flat is very tiny but after one day you conclue that you do not need anything more when you spend most of your time outside. Very good and swift communication with the owner by email & mobile (thanks Daniel :-)). From the place you can do a very nice walk along the Seine River to Notre Dame and Louvre. If you want to cook yourself you can get what you need at e.g. Carreffour store which is located at a walking distance. The only think I could complain a bit is no WiFi which today is almost a must but...nothing is perfect... :-) I definitely recommend staying a L'Hotel Particulier during your Paris experience.
