Contexto local · El Masnou
Many flats in El Masnou still have old panels.
El Masnou is a thin strip between the C-32 and the sea with two realities: the upper part (Sant Felip, Ocata-Alt) is single-family homes with views, and the lower part (Centre, seafront) is 1960s–80s flats whose balconies face the N-II. Salt exposure is high: any external locksmithing or blinds get a marine treatment. The upper area drives periodic maintenance (garden, pool, heat pump); the lower area drives full refurbs that open up closed layouts. Parking is OK uphill, tough near the Renfe station.
