Alejandro is a wonderful host! I felt so welcomed at his home. He was very helpful when we communicated before I arrived and also when I was living there. My flight to Madrid was delayed by 4 hours, resulting to a late arrival past midnight. Alejandro was very understanding and accommodating.
The home and room was very clean and well decorated! It's very cosy and has all the necessities. The location is close to cafes/restaurants, subway stations, supermarkets and a pharmacy. There's even a Vodafone store close by if you're planning to get a traveller SIM card.
I'll definitely recommend Alejandro's home for your trip to Madrid. I look forward to when I'll return!
