We had a good stay, however, the apartment looked a lot bigger in the photos. We had problems with the shower and sink clogging up but the tenants were responsive and sent someone out within the hour. We traveled with 6 people and it was a tight space. I think for 3-4 people, the space would be perfect. Interestingly enough, the apartment has a dishwasher but no washing machine.
The location was unbeatable, in the heart of Paris! Line 1 (Concorde) is about a 5 minute walk and we walked to the Eiffel Tower (about 40 min with kids) but it was enjoyable as you can walk past the Pantheon and other landmarks! It was a good stay!
