Hi every one!

I'm providing an office space service with fully funish inside
-Filling desks and chairs, cabinet, air conditioner, wifi internet
-Common area like conferrence room, guest area, restroom, place for breaktime with hotncold water, microwave
-Security, parking space (for motorbike if free, car parks at space near building about 50meters.)
-Support in document photocopy, printing and fax; mail and package handling.
My office is placed in the center of dynamic city - Ho Chi Minh city.
Just starting at 260 usd for private office 2-3 workers.
But the customers is so hard to pleased.

Is there anyone have a new idea for it?
