This was the first time that I used AirBnB and the experience was most agreeable. I usually stay in hostels, so to have a room all to myself for a price similar to what you would pay for a bed in a dorm was great. The room and the apartment were very clean. There are four rooms in total so at times you might have to wait to use the bathroom, but this was no problem for me.
I met Miguel Angel briefly and he was very nice and welcoming. I spoke with his mother everyday and she was absolutely delightful and charming. I spoke Spanish with her, as she doesn't speak English, but she is so nice and friendly and patient that the guests who didn't speak Spanish had an enjoyable stay anyway.
I hope to stay with Miguel Angel and his mother the next time I'm in Madrid.
