A quiet, clean good-sized one bedroom apartment, ideal for a single traveler (like myself) or couple. The interior design is neutral, with a lot of mirror walls, and comfortable bed and couch. Excellent shower (I didn’t experience any problems with hot water, contrary to some other commenters), fast wifi.
What I liked most was the neighborhood: it’s a bit out of the way, but still in walking distance from the center, if you don’t mind climbing. There’s a metro station at approx 8 minutes walk (it takes 30 min or even less to the airport from there, with one change). Lots of trendy bars and restaurants nearby, as well as the Botanical Garde (5 min walk).
One negative point, maybe: the apartment is somewhat humid, and there’s a slight musty smell, which pretty much goes away if you open the windows. It wasn’t a big deal, though you might consider bringing a scented candle.
