“I was very frustrated 6 months ago when I was at Craigslist looking for an apartment here in Costa Rica. Most of the Agents are not responding or not available , cannot even give any suggestions and is not willing to work anytime of the day. I finally got hold of this website " ONE STOP COSTA RICA " then automatically got a reply and a phone call. After 2-3x back and forth emailing each other, 2 hrs after Jan is already waiting outside , right on time in my hotel. 3hrs after , I got a very nice beautiful, top of the line house which I specifically told Jan what I am looking for. Jan is a type of real estate agent, that will asked you first what you want, what your looking for and your budget. He is also very observant with your type of personality.
