Great location, well-equipped apartment. I was in Paris for a work trip and wanted a warm "home" feel instead of a hotel. Really enjoyed our stay here!
The place is quite compact so I'd recommend it for one person or very good friends or a couple who doesn't mind a lot of intimacy. Overall, it was well-equipped with supplies, nice appliances, and everything worked perfectly. The washing machine was fantastic to have. In early winter it was very comfortable and never felt cold, even with the heater off for hours. The apartment was quiet with no noise from the street, so no problems sleeping or working. The only issue is that very little sunlight comes in the apartment because it is an interior (even if it's sunny out). However the interior illumination is more than sufficient, and I imagine the lack of daylight may be a personal preference.
The location is fantastic on a very cute pedestrian street with tons of restaurants, boulangeries, shopping, and various metro stations nearby. Walking distance to the Marais as well as a multitude of things to do around Paris by foot.
Sirra was very responsive and overall we had a wonderful experience. Thanks again Sirra et Fanny!
