First, Lupe is very gracious, responsive, and very willing to share suggestions to give you an authentic experience in Madrid. The location is quiet but still very accessible to transportation, museums, and parks. We could walk everywhere (it’s about 2 km from Plaza Mayor). The Retiro is just across the street and is a great way to have a relaxing day while getting to move among the Madrileños. The apartment provides good space for a couple but could be manageable for up to four.
