Such a lovely apartment. It’s really close to metro stations. There is Montparnasse station near the flat and it was very convenient. The building has a small lift which was also convenient for us as we had heavy suitcases and a stroller.
The flat was very warm and clean. Rooms were big and comfy. A toilet and a bathroom are separate.
I recommend you to stay the flat.
When I visit Paris next time I would like to stay again :)
