We were 2 pax on a business trip. Location was perfect for us. We haven't met Etienne, he gave us instructions through email/SMS. All worked out. He was kind to prepare two bed sheets (bedroom and living room).
The apartment wasn't very clean, but for us ok. As we have been away all the day. Bed linen were clean. No coffee provided.
If you book this flat, you have to be sportive (6. floor). Without a lot of luggage no problem.
