Temp rental advice


Hi, I'm looking for advice on renting an apartment in BsAs for about a week. I'm an exchange student here living with a host family, but when my boyfriend comes to visit me in May, I'd rather that we stay someplace else. I've been looking on http://www.bestrentalsba.com, and it seems like they've got some good deals, but I wanted to be sure that I'm not getting ripped off.

I'm looking for an apartment downtown - Balvanera, San Nicolás, Monserrat area - from May 7th to the 18th, for about U$S 250-300 (hopefully more like 250). If anyone knows of a better website / agency to use or has an apartment available during that time I would greatly appreciate any advice.
