The apartment is very conveniently located, within 5 min walk of a metro station and many shops and restaurants just outside. The area felt safe. Rue Montorgueil is very busy and loud everyday but the apartment faces a courtyard so it's quiet.
Note that the apartment is located on the "2nd floor" which means 2 flights of stairs as it is on the 3rd level of the building and there is no elevator. Check-in and out was easy and communication with Isabella was friendly and quick.
The apartment seems recently renovated and has nice modern design touches.
We stayed in June and it was comfortable without AC at that time.
Would definitely stay here again if I ever returned to Paris.
