We had a wonderful stay at Fernando's flat. Check-in and check-out was seamless. The location is perfect to reach all the places you need to see in Madrid and there are countless bars and restaurants within a 5 minute walk. Completely safe area and great vibe the moment you step out of the door. It is important to note that there is no air conditioning in the flat so there is little relief from the warm days in Madrid however the fan is helpful. There is no Wifi and therefore a good place to stay for those who want to completely escape the stress of emails and social media (although there is free wifi on the street). Would recommend staying here.
