Apartment buildings in Marbella were built in such a way that you have everything in there. Some of them will have about 50 floors of apartment units, several floors of parking space and common areas.
Apartment buildings usually have about two floors that are dedicated common areas for people to use. They have several gyms, tennis courts, a spa, beauty salons, etc. All of these amenities are inside the buildings so it is very convenient for people who live there. You just have to take the elevator, head to the common area, and you will find yourself in the middle of everything.
Some of the apartment units actually have saunas and steam baths and these are already included when you buy the unit. You do not have to install any of these amenities on your own. That is part of what the developers offer because they know that people will use these facilities anyway. The structures were made to fulfill all your needs.
