My niece and I to stayed at Sebastian’s flat in Paris July 2019. I appreciated his detailed instructions for accessing the apartment, the manual for how to use everything, and especially the simplicity and flexibility of the check-in and check-out procedures.
Sebastian made himself available by several different communication tools (phone, text, email, WhatsApp, etc) to provide additional support as needed.
The flat was exactly as described (very small elevator, 1 flight of steep, irregular stairs, and a mobile A/C unit). Compared to many flats in Paris, this place is very large and spacious. Plus, we had access to a stove, refrigerator, cookware and flatware so that we didn’t have to eat out all of the time.
If I were to return to Paris, I would definitely consider booking his flat again. The location was convenient with bus and metro stations nearby as well as several restaurants and bakeries.
