Villa Olga is a little closer to Gold's but neither is a short walk away. Look into the neighborhoods behind Plaza International.
That area is called La Esmeralda. Nice area (and only real neighborhood within walking distance to Gold's Gym) but tough to find a one bedroom, especially furnished. Same goes for Villa Olga and Los Jardines...most apartments are 2BR and larger and unfurnished.
Ive spent a lot of time in both Villa Olga and Los Jardines and would definitely recommend the latter, especially if you like to walk. There are several parks and areas great for exercising. Also, Villa Olga may be less commercial than Los Jardines, but the traffic is similar, if not worse and I've found it noisier at night. Los Jardines also has the advantage of dozens of restaurants, bars, stores, banks, etc, within walking distance...as well as Caribe Tours and Metro Bus.
Also rumor has it that Chef Pepper is about to open on Av. 27, just outside of Los Jardines....if it's true I'm considering moving back there! :bunny:
