I stay at Benjamin's place for 8 days. I came to Paris to assist a tech conference and to visit a few places with my wife.
My first impression, was exactly what I saw from the photos and what I read from previous reviews. Exactly as described, which is very good, and is the first step to build trust.
The check-in was on time. I told Benjamin that I would be at his place by 13:00 and he was there a few mins before.
Benjamin's place has very good points: 1) his place is near to a Metro station (1-2 mins walking), 2) the internet is blazing fast (170Mbps download, 30Mbps upload), 3) there's a washer that will save a few bucks and walks, 4) there are several ATMs, bakeries, parks, vèlib (free bikes service) near to his place and last 5) the Eiffel tower is at 30 mins walking.
Benjamin is very nice, I booked 8 nights for my wife and me, then later I needed to add an extra person for 4 nights, that wasn't an issue, everything went fine.
Finally, the checkout is super easy, I put the keys on a table, closed the door and done. Super easy! Love his place! Recommended for couples and friends.
