Mario and his mother are great hosts. The apartment is in a perfect location, near the most important sights of the city. There are a lot of bars and restaurants nearby open also overnight. The Plaza Alfalfa is beautiful! Check in and check out are flexible and you can also live luggages after the check out. Mario is very responsive and his mother gave us a lot of advices (where to see flamenco, to eat..). I recommend to stay in Mario's place and I would surely come back there again.
