Communication was wonderful. Check in was easy. Sweet Inn had someone there to meet us in the late evening (22:30). The apartment is spacious in Paris standard. It was clean and nice. Bed was comfortable. It was very close to our daughter's apartment for our visit with her. It was walking distance to Rue Montorgueil which is a lively area with many many restaurants.
The only thing I would point out is that there is no street number on the door. So you will have to rely on your navigation system and street numbers around you to gauge the street number for the apartment. It worked out fine for us.
