Pros:
Great location close to the metro (line 3) and buses. Spacious (for Paris) with a good living/kitchen/dining area. Great communication from host. Building had lift! Easy checkin. Good wifi/TV with Netflix/Prime.
Cons:
Bed was a little uncomfortable for us. Also the shower is quite hard to get into for short people! (has a high step to get over). Kitchen seemed to be lacking some equipment.
I would recommend this as a place to stay - it's well located for Paris in general and for the Paris marathon start/finish (which is why we stayed there)
