Calle San Vicente, 10  San Sebastián de los Reyes, Madrid 28700

San Sebastián de los Reyes is a town within the Region of Madrid located 18 kilometres from the capital. It covers a surface area of 59.26 km2 and is commonly known by its abbreviation “Sanse ”. It is located above the River Jarama Valley, at an altitude slightly over 700 metres above sea level. Urban sprawl since the 1960's did away with its rural atmosphere to the extent that it was subsequently absorbed into the capital’s metropolitan area, coinciding with the urban expansion of Alcobendas.
