Javi's home was a perfect place to stay for me as a solo traveler in Madrid. He was gracious with flexibility in check in/out, helped me up the stairs with my bags, had flowers and chocolate in my room, let me use the washer, and overall made me feel at ease. We had great chit chat when we were both home.
Location was perfect- I never needed to use taxi or subway because it was pretty walkable to most site. Room size was minimal, but perfectly transparent from the photos and all I needed for my stay.
Highly recommend!
