Bastay/Buenosairesstay are the worst, so many bad stories that I know personally from many people I would never use them, why risk it when there are good agencies out there, like Dr_dawggy said apartmentsba has a good reputation, habitat etc. With good agencies no one has a bad experience, with bad ones some do some don't but there is a much higher risk that you will have a problem. Again, if several people tell you a restaurant is bad do you still go.
