For that kind of money, I would rather go to a different country as well. Like Thailand. Find a nice place in a city with a co-working space. If you'd be ok eating asian food, life can be very cheap (1,5 USD a meal depending on where you buy the food). A nice apartment + gym + swimming pool can be rented pretty cheap as well, maybe starting around 300 USD a month and more expensive depending on the size of the apartment.
