First of all, the location is absolutely ideal, in the heart of the Marais just a short walk from the Hotel de Ville Metro station, yet insulated from the throngs of tourists. It was easy for us to feel "at home" in this neighborhood for shopping, dining or just strolling.
I can't say enough about the efficiency, friendliness and professionalism of Soline and her partners Alix and Jonathan. Mere minutes after we booked, we received a warm welcome and clear instructions for getting to the flat from Roissy. Shortly before our trip the Gilets Jaunes protests were in full swing; they sent us helpful and reassuring updates and links about those events, and we traveled to Paris confident that our trip would go just fine.
Alix met us at the door just as we arrived outside and it dawned on us that we hadn't activated either our phones for international data yet, and might have had a hard time contacting our hosts...perhaps it was just a lucky break, but we'll give Alix full credit! :) She gave us a thorough orientation of the apartment and the area, answered all our questions and anticipated some we hadn't thought to ask.
The property itself was even better than described, spacious, bright, clean and comfortable—bigger than we thought it would be. The bedroom we had was quiet and private, and it's proximity to the apartment entrance door meant that we didn't worry that we might be disturbing our hosts by coming in late or leaving early.
One night, we spontaneously decided to reserve a table at one of the area's great jazz clubs. We reached out to Jonathan through Air B&B, and he replied instantaneously. He called the club, and booked us a great table with a perfect view of the stage. Our French is functional but far from fluent; I'm pretty sure we would have bungled that phone call without his help!
Dans l'ensemble, nos vacances a Paris ont été excellentes, et une grand partie du mérite revient a nos aimables hotes. Nous recommendandons Soline et ses amis avec beaucoup d'enthousiasme!
