Fantastic hotel with great service and great location. The Hotel is only a short walk away from Moulin Rouge and Montmartre, but just the couple of blocks away from all the noise so you can sleep in silence.
The room was spotless clean and there's a complimentary mini bar with soft drinks, which is really nice if you're on the go a lot. There's also an open bar with soft drinks and snacks in the lobby and you can also access similar open bars in the other hotels of the chain all over Paris.
The room also had an adjustable air conditioner, which was a lifesaver on the warm days.
I can't recommend Hotel Monterosa enough!
