Hotel has excellent location, across from Metro Mouton Duvernet line 4 go direct to Gare Montparnass. Walk 6 min to RER B Gare to go direct to CDG, to go to Orly airport, there is a bus right there too
The only negative is air conditioning barely works, we are in Paris in August, so hot so not as comfortable as we would expect. Reception is willing to change room but we talk the guest in that room he says the same thing about AC so we did not change . He said , coming from Asia, he tolerates heat better than us, Ac is acceptable but not like it should be. They send a maintenance man who can’t do anything. I don’t recommend this hotel in the summer
