Just finished a one month stay. Great location on Rue de Conde very near to the Luxembourg Gardens (a plus for runners). Location is definitely the highlight, close to park, metros, grocery stores, shopping and restaurants. The apartment was quiet, yes there was a little street noise but minimal for a big city and much quieter than other places I have stayed in Paris.
The full size bed was very comfortable and had nice linens which made for a good nights sleep. The elevator was nice to have to bring luggage up and down. This apartment is on the first floor (US second floor) and is accessed by a spiral staircase that was easy to navigate. There is a small terrace with table and chairs connected to the bedroom however I did not use it. The small kitchen had a refrigerator, stove, oven, microwave and most importantly a Nespresso machine! There were sufficient plates and glasses although somewhat mismatched. Wifi worked perfectly.
The bathroom was tight and a bit old but the shower had very good water pressure and hot water. The small washing machine was handy to have.
My one cautionary note is that the apartment is more tired looking than the pictures portray....the leather couch is cracked and peeling and the paint is peeling in the shower. These did not effect the functionality of the apartment but mentioning in order to manage expectations.
Overall I would recommend this place.
