My second stay. Fantastic location - easy access to bus, metro, or just walking to the center. Short walk to Retiro Park. Nice to have the pool option. Apartment is small and room is small, but assuming you're here to see Madrid and not just hang out in the apartment, it is just right for a good rest in between outings. Room darkening blinds are great for jetlag sleep. Leire is a great host - flexible and undemanding. Recommended.
