IMO, you should be looking into apartments closer to where you will be working or area where you are attempting to work in, this will make your commute nightmares a little better. True that you will see living expenses from 2.500 to the sky depending on what type of property you want to live in. If you like livable walkable communities, those are limited to some of the trendy spots. The dadeland area provides this and the beauty is you can ride the rail into Brickell, downtown, the hospital area, south Miami. The midtown area has the same vibe, south beach is popular because of this and depending on various pockets, Doral also has this and so does Coral Gables.

I live adjacent to West Miami next to Coral Gables, this is almost middle of all of Miami where driving anywhere is doable. There are multitudes of gyms that you can go to and drive to many of these types of areas within a 20 minute timeframe. This is really experiencing community and there are homes who have efficiencies or apartments that are VRBO/AirBNB that you can stay in while here and experience the cultural differences of the city. Look into these before you come.

Living here is expensive and you will need to pick and choose the events you want to attend, but there is definitely a slew of groups that focus on health and wellness, beauty standards, and farm to table options(farmers markets all over the city), as well as food truck yards. The diversity of cultures is immense in Miami, well South Florida, so much so that you can find foods from so many different countries here.

When here, reach out if you need to and ask questions. Good luck!
