My flight was delayed and I felt awful, arriving at David's place after 11 pm (23:00). David welcomed me, showed me around his place (very comfortable lodging), and stayed up close to midnight carving away on a map of the city how I should spend my two days in Madrid.

He recommended Toledo (a nice day trip) and when he couldn't think of a jazz club I should check out, I received a message the next day with a suggestion--it was great.

All around a great host, very accommodating, friendly, and I'd recommend his pad to any of my friends.
