Location is unbeatable! You will stay literally down the street from Eiffel tower, there are few very good bistros near and all the supplies you can need are around the corner.
The place has a soul, however is small. The bed is comfy and very big - it hosted us with one kid easily, since the upper bed is not suitable for smaller kids (the railing is almost none). If you want the best location and the best price performance, go for it!
