We (3 adults and 4 years old boy) had very nice 4 days visit in Constantine's apartment. The apartment was quiet, tidy and nicely furnished and well equipped. Everything functioned well. Constantine arranged taxi for early morning starters to airport and answered our questions rapidly. We enjoyed the
famenco perfomance in Flamenco theatre on Calle Pez. Surroudings were interesting and lively. We recommend the place for Madrid visitors!
