The flat is spacious and well designed. Comfortable bed, well-stocked kitchen, great showers, floor to ceiling French-door windows amplify the flat’s appeal. Good communication with host: as our train ran late, host left key in commercial locker space a conveniently short walk to flat. Also, the flat’s in a terrific location near Lavapies Plaza, easy walk to museums and Retiro or up the hill to Mercado Antón Martin and Las Letras, metro stop steps away. Only one caveat: noise from street life is extremely loud on weekends, shutting the windows did not keep out the sounds of revelers (which continued until after 3 AM). Sunday-Thursday was no problem.
