We stayed here for three nights while in Paris.
I’ve stayed in the area previously and would generally recommend hotels in better/quieter parts of Montparnasse.
The room was basic, clean and comfortable. We opted for a bigger room and would recommend this.
The immediate area outside the hotel is quite rowdy, and there’s an English bar which opens 24 hours on a weekend so you can imagine the noise.
Having said that- hotel is close to the metro, and lovely bars, restaurants etc, and a good base to explore the city. There are nicer hotels within the same price point nearby (would recco Hotel Du Park).
Most of the staff were really lovely and friendly.
My partner’s parents did find a cockroach in their bathroom late one evening, but I guess that’s Paris!
Air conditioning worked really well.
