The location of the apartment is excellent. one minute away from the metro at Montparnasse you can get yourself anywhere in the city. The bed wasn't great and it could use a new mattress as it bends inwards. There is mold in the bathroom which indicates a lack of cleanliness. The studio is small as advertised but there are a few aspects they don't mention: surroundings are loud and you can hear the metro running all night as well as tenants upstairs. Repairs were being made next door and they were loud at inconvenient hours.
Overall, it is a great place for a young couple on a getaway, however, it should be advertised properly.
