We stayed for 8 nights. Vita was very welcoming and very efficient in communication (incredibly quick to reply which helped us so much). She was kindly able to let us check in early, so we can drop off our luggage, which was very helpful.
The apartment was great as well as it's location, you can truly walk to all the tourist hot spots from there!! The Arc De Triomphe is literally right there, a few minute walk you arrive at the Eiffel tower and Grad Palais. Perfect for art fanatics, walking distance to many galleries and easy to get to by train or bus.
The apartment was very clean and everything you need was right there in the cupboards. When we ran out of washing up liquid and hair conditioner and she was very kind enough to provide us with more.
You will love the blinds, you can sleep in the afternoon in a pitch black room and also won't get woken up by the sun early in the morning.
The shower you will have to find out yourselves :D, really great shower after a long day of walking.

One thing I would suggest is bringing your own corkscrew and a cafetiere, we were quite gutted when we bought wine and found out there was no corkscrew (she did provide us with one later but it wasn't that great).

I would recommend this apartment to anyone who plans to stay in Paris for any length of stay. We would definitely stay there again!
Merci!
