The staff were helpful (stored food in fridge for us, kept our luggage after checkout), and the location (next to metro station Riquet) is very handy.
But when leaving the hotel during our stay, we had to leave the key with reception, which we found very odd. We discussed it with one receptionist but the explanation wasn't clear.
Also, regarding the cleanliness of the room, there are areas that can be improved (found hair on the floor and in the bed, a towel was stained with orange patch, small ants were visible in the bathroom and throughout the room).
