James was a great host, very responsive and helped resolved a little issue we had upon arriving very quickly. Great location as well.
The place is cozy and clean. The only minus I would say is the number of beds listed is a bit misleading about the capacity. We were 4 adult males not willing to share a queen bed and it ended up being a bit cramped. The place is actually perfect for a couple + 1 child (or +2 children if you don't mind small spaces).
Also 4th floor with no elevator is common for Paris but be prepared for the narrow stairs if you have bulky/heavy luggage!
