I found that the resorts in Murcia Spain that are undersold since the housing crisis are good places to start. The co-working spaces are not really here, but it fits the other two criteria. Our #1 criteria is high speed reliable internet, then price, then location/security. I travel with my community (family of 5) so that’s less important for us.
The best we’ve found so far: For ~350 euro/mo in the low season, you can live in a furnished 3 bedroom apartment, with access to pools, golf course, golf club/restaurant/bar, restaurants, etc, everything included except electric costs. 10mbps/2mpbs wireless internet, UK satellite tv, water, and towels/linens, all included. It’s a fairly good deal if you are self sufficient and don’t need to go to a co-working space to GTD (get things done). Or you can get a two bedroom for ~300/mo. and turn one room into an office if you need an official desk area, or get the 3 bedroom and place two desks in one room, and get a roommate to split the rent.
We found many of these units on Air B&B, but if you google you can find them directly and avoid the booking fee. Some resorts are more deserted than others, but still worth taking a look if you like some relax at home, and only 30 minutes to Murcia, and 15 to the beach.
The Polaris World resorts didn’t fare well during the housing crisis:
Hacienda del Alamo Golf Resort
Terrazas de la Torre Golf Resort
Condado de Alhama
Mar Menor Golf Resort
Some better than others, but if you can swing a car, the remote-ness of them makes a great home base, while you explore surrounding areas on the cheap. boa sorte.
