We traveled with two other adults (family) at the end of August. Check in and communication with the hosts was very positive.
We found the apartment to be clean and many amenities available to us, for example: Ample size kitchen with plenty of pots, pans, utensils. Washer & dryer, ironing board and iron, hair dryers, and the storage space in the 2 bedrooms were more than we needed for our week stay. The apartment is comfortable, the 2 bedrooms were also very comfortable. There are stairs you need to climb up to get to the apartment (after the elevator takes you to 2nd floor) but that did not cause any issues. The neighborhood can be very noisy at night, perhaps it was the time of year we were there, but since you kept windows open in the evening for fresh, cool air-the noise from the Marais area can be loud and sometimes go past 11:00 p.m. The location of the apartment is great, the MonoPrix grocery store is right by as well as the Metro. There are too many restaurants and bars and shopping right by the apartment to even mention. We enjoyed our stay and recommend this lovely apartment.
