There's one in every barrio, on every couple of blocks in fact. As far as I know places only do pick up and delivery within a few block radius, so you'll have to scope around near your apartment and try a few out to see who you like. Most work under the banner of larger companies, LavaYa, 5aSec (which is really more of a tintoreria service), there's one called Merval, there's another called LavaRap etc. Just walk around your neighbourhood and you'll find one and try a few different and then ask about their valet service.
