This review took me a while to write. I really liked Charles. He was extremely polite and responsive through messaging. The apartment is in a fantastic location in Paris. We would stay in the Montmatre area of Paris again.
The building was very secure. It does have a very small elevator, as are most elevators in Paris. It was convenient for getting our luggage up to the flat. We enjoyed the three flights of stairs from a fitness perspective, even after walking all day. What would have made our stay more pleasant, and I must say even bearable, would have been more fans, which I have communicated to Charles.
These old buildings with their high windows cannot accommodate air conditioning. One small fan for the entire flat where you will have four guests sleeping throughout the flat is not enough. We were exhausted our entire stay from a lack of sleep due to the heat.
Charles has a convenient set-up with the cafe on the corner for check-in purposes. However, he relies on a team when/if he is not available to personally check in his guests, and our check-in got pretty botched. After a long trek from the US, we spent nearly an hour inside the courtyard trying to reach someone to in order to get in to the building. It was clear to us that she was not finished cleaning the flat. We would have been fine with this, but no one, including Charles' manager for the flat, Vesna, could be reached to inform us of this. Transparency is so important in managing expectations with guests.
The cleaning person rushed off, so no one provided us an orientation to the flat. Once we were somewhat settled in, and after several WhatsApps to Charles to find sheets, etc. I read through the AirBnB posting detailing where the sheets were located, etc. I think that Charles and Amelia rely on their detailed AirBnB page rather than actual people to conduct their business. I have hosted an AirBnB and having a live person to check people in is in my opinion preferable, even essential. As a guest, I thought it was odd that I would have to prepare my own bed... but this was the least of my concerns.
Overall, I will not stay at Charles and Amelia's again, but I think that if Charles tweaks his check-in process, is more transparent with his guests and provides more air flow for the apartment for these hot summer months, I'd recommend their flat to others. I requested a partial repayment from Charles for our troubles, but have never received a response.
I hope this feedback is helpful to all, mostly to Charles and Amelia. Enjoy Paris!
