Alexandre's spot is great for large parties. I went with 6 others and the 3 bedrooms + 3 sofas provided more than enough comfort for us all. The dining and living room was spacious and had a nice balcony overlooking the Square Émile-Chautemps. Walking distance from 2 train stations ensured that getting anywhere in Paris was a cinch! The kitchen was great for quick morning breakfasts or late night snack making. Lastly, the area is clean and very secure in a gated area.
As for Alexandre himself, he was kind to be flexible enough to greet the rest of the group when I got rerouted to a later arrival flight and provided answers to all of our questions. Would definitely return to his place again!
