My three sisters and I stayed here for a 4-day adventure in Paris. The location is excellent - we highly recommend checking out Place Sainte-Catherine across the street, and La Mangerie has great food and drinks. The apartment itself is quiet, despite being in a busy neighborhood, and the beds were comfortable, which is especially helpful if you're like us and walk everywhere! The kitchen set-up is just right for making a small breakfast in the morning or eating dinner in after a busy day, although you should pick up your own coffee filters if you're planning on making coffee in the morning. Each room does have its own sink and shower, but there is only one toilet in the unit.
Communicating with our hosts was slightly difficult upon arrival in Paris - we had to change our arrival time by an hour due to the longest customs line I've ever seen, and we didn't know for sure if the time change would be fine with our hosts until about 45 minutes after we first contacted them, as I could only reach a voicemail machine on the phone number provided. You should also discuss check-out arrangements upon arrival - we didn't and this led to some confusion. Overall though, once we were able to communicate, our hosts were very accommodating and helpful. We would all highly recommend this apartment, and we'd love to come back!
