Location was very good: close to multiple Metro stations; 20-30 minute walk to Marais area; 5-10 minute walk to funky Republique; and plenty of local eateries.
The double bed in the loft is as described-- steep stair access, so be confident in your mobility. The single beds were comfortable, but those after a softer mattress may find it too hard for their liking. We found it was perfect for our backs after a long day of touring Paris.
Agnes was a wonderful host, welcoming and ready to be of assistance when needed. We enjoyed listening to her play the piano-- it brought much joy!
The apartment was clean and decorated very nicely. A lovely AirB&B!
Thanks for having us three Aussies!
