This was a fantastic apartment for exploring Paris in such a nice area with lots of lovely restaurants and cafes and a lovely buzzing vibe as it is a studenty area. It was easy to walk to Norte Dame etc. and other central places. I don't think you could beat it for location and value. The beds were comfy and we had everything we needed. We were four people and very comfortable but six might be a bit tight space-wise. We managed the stairs fine and I think as long as you know about them, they won't be a big problem.
