Rafa was a wonderful host and did everything possible to make our stay in Madrid enjoyable. He gave us tips on local restaurants, nightlife, and travel. He was also very responsive to any questions we had. His apartment is very cozy, and can comfortably accommodate two couples (five or more people will start to feel cramped). The apartment is also very close to the Atocha train station and within walking distance of Madrid's main tourist attractions. The neighborhood is quiet, so you should be able to get a decent night's sleep. We would certainly not hesitate booking with Rafa on our next visit!
