Really great apartment, with everything you may need for short-stay. Nice and clean, well equipped, we really enjoyed our stay. It's really great for 3 persons- has one double bed on the gallery and sofa bed in the living room.
Sergio is great host, we haven't met in person, but we arranged everything easily.
Neighborhood is really picturesque and lovable. Just 10 minutes walk from Puerta de Sol and Plaza Mayor.
All the recommendations for this apartment and this host:)
