i've used Alex's Party rental about 3x for the events we hold for our clients. As of yet, they're the most reliable party rental companies in W.LA. Claudia, the sales lady, is very friendly and prompt. The delivery guys are always there early to help setup and are a pleasure. Very friendly and helpful! The only complaint I have is that its a little difficult to reach them on the weekends, especially when its time to pick up the rentals. But regardless, I'd still use them again.
Pros: Friendly delivery guys; gret pricing
Cons: difficult to contact on weekends
