I have spent a week at the apartment along with my wife and small baby daughter.
When we arrived we were greeted by Thomas, who kindly gave us instructions on everything we needed.
We also received a baby crib which was a very nice gesture.
The apartment is just as pictured, with great natural lightning, but also electric blinds if you desire some privacy.
It is at floor 5 of the building, with a fast but a bit small elevator. Be advised that there are some steps before you reach the lift, and for us it was a bit difficult to carry the baby stroller every time we went out.
We stayed in March and it was still cold outside. Fortunately the heating worked perfectly.
The apartment is situated in a very nice and safe neighborhood - arrondissement 11, near Republique square.
In the evening you will find it is mostly populated with locals, and has a nice selection of bars, restaurants and shops which are not that expensive.
There are 2 metro stations near the apartment which we frequently used, each at about 5 minutes distance.
I highly recommend staying at this apartment, and would definitely stay again here when visiting Paris.
