Our family of five adults recently stayed at 50 Rue de Rivoli. One reason for choosing this apartment was the promise of air conditioning, but the building air conditioning was not functioning. Sweet Inn provided room air conditioners and fans, but the portable air conditioners vented through open windows which allowed some mosquitos to get into the apartment. Happily, the heat wave had ended so using the units was not necessary and we could close the windows.
Our biggest problem was a shower drain that plugged, with water running into the apartment below. Needless to say, the apartment resident below was furious and shut off our water. We were unable to reach anyone except the answering service so, instead of heading for Giverny, we made a trip to the Sweet Inn office. Once the staff members were aware of the problem, they were most helpful. They assisted us in moving to a nearby, even nicer, apartment.
We know that plumbing problems can occur in older buildings and we appreciated the immediate and courteous help. Our suggestion, however, is that the office have a person on call to deal with emergencies when the office is closed, rather than relying on an answering service.
The two apartments we occupied were well furnished and clean, and the locations were perfect, across from the main tourist office and a Metro station. Overall, we had a good stay with Sweet Inn.
