Ruty and Dervys were great, responsive hosts with dinner and local recommendations that turned out to be great! The unit's is situated about 2 minutes walk from Plaza del Sol, the heart of downtown Madrid. You can get to the Royal Palace or the Prado (west or east of the unit, respectively) in about a 10 minute walk. Plaza del Sol is also the hub for most of the local Metro trains and also has some non-stop trains to the Atocha (main train station) of Madrid. We loved the unit, it's modern, clean, and had great finishings.
