Carlos is a really nice guy. He’s busy, so you might not see him a ton, but he’s also available if you need him. The bedroom is simple but more than adequate, and the common space is nice and comfortable. You can reach the Royal Palace and Plaza de España with a short to medium walk from the apartment, which is also only about an 8-10 minute walk from a subway stop. Also, there are several restaurants/bars and grocery stores nearby. I absolutely recommend this place.
