Miguel & Iaia's flat is located exactly in center of Madrid. Every main monuments are close from there so we didn't have to use public transport. Walks through many little and charming streets in neighbourhood was a pleasure. In a few minutes we walked to Museum Reina Sofia or Prado. There were many atmospheric pubs around and shops where we could buy everything what we needed.
What about flat? It is great! Very comfortable bed so it was hard to leave it every morning ;) It looks exactly like on the photos and it is very quietly.
Miguel & Iaia are very positive people. They were waiting for us in the apartment though we had arrived late at night. They gave us useful instructions about their flat.
We recommend this flat to everybody who wants to visit Madrid and see its other real face. Away from crowded and loud tourist attractions but close enough if you will want to get there :)
