Alba's place was just accross the street from a large park - Manzanares - where a river flows and transforms the landscape. So really nice place for a walk in the morning before the heat sets in.
Alba herself is a very welcominhg host, a really nice person - she advised us of some local places with bars and restaurants, and gave us tips how to get there. She even invited us to her yoga class in the park, but we'd already plans for the evening. All in all, I would highly recommend a stay at her place - quiet and clean room in her flat, convenient for metro access (Hospital 12 Octubre) and the park nearby.
