I was in Madrid for two nights on my way back home after my vacation in Southern Spain. I stayed at Paul and James's place. It was actually their mom who lives there. She is an amazing host. Very helpful. The place is nice and clean. While Madrid is a big city, the place is very central to all the attraction I wanted to visit. A block from Mercado San Antón and lots of nice restaurants nearby. The nightly bus to the airport is just 10 mins of walk.
