Everything was as described and everything about the trip went smoothly. Jean-Marc's communication before the visit was excellent. I was greeted by his friend on arrival at the flat and again to handover the keys when I departed. They both speak and/or write great English, which was terrific because my French is terrible.

Le Marais is also a really great area and well connected with public transport - although I mostly walked wherever I wanted to go as it's a) a great way to see the city and b) the flat is located close enough for a leisurely walk to most places.
