The apartment is a top-class Airbnb rental. The location is great - with plenty of interesting shops, cafes & restaurants in the surrounding streets (we particularly liked Krugen for crepes), while only being a short 20-30 minute bus/metro ride to more central/touristy Paris.
Communication leading up to our stay was great and very responsive, and we had a warm and thorough welcome from Donna who was looking after the apartment.
The décor inside is cool and slightly quirky but still maintaining a clean and comfortable environment with everything we needed. We were able to cook a nice meal with fresh fish & veg from the local Marché Popincourt using the frying pans, saucepans, colander, utensils etc.
The bed was comfy, and the metal security curtain at the front helped keep the studio dark for a good night's sleep.
I would only warn that the metal stairs leading down to the shower & spa are very steep with only fragments of handrail, so the apartment might not be suitable for those who are frail or with reduced mobility. Even we in our late 20s had to take care!
Nevertheless, I'd thoroughly recommend this Airbnb!
