The apartment is very centrally located. About 10 min walk to Tuileries Gardens, Place de la Concorde, etc. Lots of restaurants and cafés on the same block. There was a Carrefour market around the corner and a great artisan boulanger about 200mts away.
It is on the ground floor and it is in the very heart of the building block, which keeps it away from street noises. The only noise we could hear once a day was people throwing glass garbage away (there is a restaurant on the front part of the building). On the down side, being an inner apartment means that it has virtually no windows that you can open to get fresh air to come in (only a tiny one above the kitchen). Daylight came in through the glass wall anyway.

The place was very clean when we arrived and it was provided with linens, towels, soap and shampoo and some basic small appliances (such as hair dryer, toaster, Nespresso coffee machine, etc). In the bedroom night lamps had wireless cell phone chargers built in, which was a nice surprise to avoid dealing with cables and sockets. Hot water worked perfectly, even too hot sometimes.
If you are planning to eat in, you might want to consider that there is only a little fridge, a microwave and a stove. No freezer, no oven.
Both the bed and the sofa bed where comfortable to sleep on. Sofa bed was really easy to fold in and out with no effort. The pillows could use some improvement.
There was kind of a misunderstanding with our host about the possibility of having a crib left in the apartment for our 2yr old. We initially asked and where told it was OK, but in the end we were not able to have it. On the other hand, we were able to check in early (although it was only confirmed on the same day of arrival), and the process was smooth and well explained.
If you look for a perfectly located place to sleep and have a nice bath after walking through Paris all day long, this is a very good fit.
