I have used Airbnb several times but Alberto is the best host in terms of hospitality and preparation for guests. Using this host-guest matching service I always get a bit nervous. But meeting with him I felt really at home. He is running a business at the ground floor of the apartment, which is a big plus for guests because I can see him very easily. The room itself is a bit narrow for two people but everything was functional except Wi-Fi. The location is perfect for first-timers to Madrid like me since it is almost the center of the historical area. I recommend this room but make sure with Alberoto that the Wi-Fi was fixed.
