Nicolas’ flat was just right for my 4 days in Paris. I booked very last minute, and he was happy to accommodate.
The only issue I had was some trouble using the key when I first arrived. Nobody was home, and I had some trouble getting ahold of Nicolas for help. Turns out I just forgot how to use a key, and I figure it out after a bit :)
I never ended up meeting Nicolas during my stay, but his roommate, Matthew, was lovely and hospitable.
Be aware, the walls are very thin and this room is right off of the common spaces (kitchen, living room, bathroom), so you can really hear everything, and there aren’t necessarily quiet hours in the space. This didn’t bother me at all, as I’m a very heavy sleeper and didn’t any nights that I was worried about getting to sleep early, but be advised.
The room is also quite small. Worked great for just me, but would be a tight squeeze if you want space to move about.
Location was awesome as well, barely 5min to the metro station, and 10min into central Paris. And also really walkable (20-30min) to Notre Dame, the Louvre, Champs Élysées, if you feel up to it.
Overall, Nicolas’ place worked great for me!
