I stayed there last week. It's a nice, modern hotel. The room was well suited to get work done as it had a good adjustable chair and reliable wifi.

I think the hotel is a good choice if you have business in that area (Arcueil, Montrouge), but I wouldn't choose it if you wanted to do sightseeing in the center of Paris. Laplace station (for RER B) is less than a 10 minute walk, but the t+ ticket won't work there. The new metro station Mairie de Montrouge (line 4) is about a 15-20 minute walk.

There's a shopping mall across the road with a Monoprix supermarket.

Since it's a Courtyard, you only get free wifi but no free breakfast. Breakfast is 18 EUR per person and is an American style buffet.
