We enjoyed our stay in Paris but found the apartment rather disappointing. It looked really smart in the advertised photos but in reality it was scruffy in appearance & several areas did not work well or were broken. For example, the shower door is dangerous and not fixed to the runner, the bathroom shelf is not fixed & therefore falls on the floor, the large shower head does not work properly, and the front door is very difficult to lock/close. The overall decoration is in a poor state.
The area of Montparnasse is well located with great restaurants but unfortunately I wouldn't recommend this properly.
