If you want to stay by Champ de Mars, this is a good spot! Right next to a really good train station, plenty of food options up and down the street, and a very quiet room to yourself. Plus, being by a Monoprix is always useful.
There's not a ton of storage space here, but it shouldn't be an issue for a lone traveler or couple.
I will say the initial entry is a bit confusing with two doors, an elevator, and then some more doors, but once you've done it one time you'll feel comfortable navigating.
