Castellana belongs to the district of Salamanca. Here is where embassies, luxury business and some of the best restaurants. The neighbourhood has a business vibe consolidated by the landscape that is made out of tall buildings, offices, car parks and shopping areas. Outise the neighbourhood centre, Castellana becomes a residential area with smaller buildings inhabited by families and young couples, with plenty local groceries stores. Here the prices become cheaper and the general vibe calmer.
