Pros: Location is excellent. About 5 minutes from the louvre and 3 minutes from the nearest metro line. Functional studio but not particularly comfortable. Is on the 5th floor, without a lift but the walk up is not that bad (unless you have lots of heavy luggage).
Cons: The layout could be better - there is little space to put your things and the cupboard has a mattress in it. The kitchen was clean but could be better. The microwave was not clean. Cupboards are old. Bathroom is functional but old.
