The flat was in a good location and the area felt safe.
However, there were some cleaning issues. The shower curtain has mould on it. Moreover the sofa in the living room smelt really bad, like an old musty smell and we sadly both caught bedbugs from the sofa. Luckily we didn't stay long but had to spend my birthday in the laundromat, washing and drying clothes so we don't contaminate my parents, and spent so much money, we had not planned to, in pesticides and time steaming all our belongings to kill the bed bugs.
The rest of the place was relatively clean. I believe if the issue was addressed it would be good place to stay.
It's a small flat in Paris. There is no concierge. You will need to get the keys about 2/3 stops, further away from Montparnasse. It's easier to cycle there.
The bed is comfortable but there are only a pillow each per person, and there are quite flat.
The building is quiet.
I cannot give a good ratings because of the bedbugs. I am more tired after the holidays then when I arrived. it was very stressful experience. I have asked for a refund.
