This place is a few minutes walk from the Palace and Plaza Mayor. Yet a quiet residential area. Spend 7 nights there and half of the time it was raining. A good retreat for rainy weather as well because it’s a spacious basement flat with a big TV able to play Netflix and a big sofa.
The host is so attentive, let me had flexibility regarding checkin and checkout time.
Just be aware Madrid is generally with slopes and stairs. Pack light.
