The apartement is small but it's totally fine! In the kitchen is everything essential for cooking and the bathroom looked clean too. There is a big TV with an HDMI-cable to connect your Laptop. We even had one Movie-Night which was great!
It's an old building, so everything seems a bit dirty but this is a fact, which you can not change in an old building. ;)
I would recommend this apartement to everybody who wants to visit Paris and not pay too much for the accomondation. (I would also recomend not to travel with too much luggage because of the space. We travelled with hand luggage only and the apartement was drowning in our stuff! :) )
