We stayed at the apartment for a month and were very comfortable there. Rue de Cherche Midi is lively during the day and quiet at night so we slept very well.
The apartment was adequate for our needs but would have preferred an oven in the place of the dishwasher. There were a few issues at first with the heating but Samuel came over and sorted them out. I tend to agree with a previous comment regarding the furniture - it's a bit tired (not in an antique way). It's a great location though and based on other apartments I looked at, good value for money.
