This place is beautiful and on the top floor with good street views. It is situated close to shopping and very good restaurants. Lots of night life. It is an easy 15 min walk to the Louvre.
I was there in August and it got a little warm (specially bringing the suitcases up the stairs) but there are a couple of fans and lots of windows to help with that. That shower was great, specially if you love HOT water.
Make sure you understand that there is not an elevator. Five flights on a spiral staircase makes it quite a workout to get heavy suitcases up. (Or just walking up if you are out of shape like me). Even so, it’s worth it.
