We had a great experience at Martin's apartment. We had 4 adults and 4 college kids, and had plenty of room. The apartment is lovely! The large dining table provided a great gathering place for our two families. Martin was flexible in meeting us when we arrived. He provided plenty of towels, sheets, etc and even provided some greatly appreciated kitchen staples, such as coffee, jam, milk, etc.
The neighborhood provided the perfect home base for our Paris touring. It is diverse and lively and, at least while we were there, did not seem overrun by tourists. It had plenty of excellent bakeries, small groceries, pharmacies, and small cafes/bars/restaurants. We were only a few minutes from a Metro stop.
Martin was very responsive during out visit and overall just very helpful and nice. This was one of our favorite AirBnB experiences yet.
