Etienne's apartment is well described; we thoroughly enjoyed our stay and would recommend. It's beautifully centrally located in the Marais, which is exactly where we wanted to be. The little personal touches (milk butter and jam in the fridge, coffee/tea provided, and gifts of wine and chocolate) were most appreciated.
The 103 (beautiful, wooden) steps up to it from the ground can sometimes feel like a chore, but the apartment notes do warn about those, so we knew in advance and just took them slowly.
Etienne was on holiday himself at the time of our stay and the AirBNB host service he used was most assiduous in terms of keeping in touch (a few too many emails and phonecalls at times) but very kind when they met us - the chap insisted on carrying my bag from the ground floor
'...allow me - you are on holiday!'
and when my husband faltered near the end he took his from him too!
