- GGGuggimamJul 1, 20265.0This is actually a real post office you can drop off your package your mail anything it is the it’s actually cute small post office
- LLLemoJun 27, 20265.0This place may be tiny, but it's definitely the best post office that I've been to. 1) The line moved quickly, because there was more than 1 person working at the counter. 2) The employees don't act like they're working at the DMV....or a funeral home. 3) My international package mailing experience went smoothly, and with no attitude from the clerk. I think I'll start driving from Corona to Ontario just to use this post office. The 1 lady at the Corona counter huffed and puffed, and kept saying that she needed to go to lunch, then complained about my use of ö and ß in the names, because her keyboard can't make those characters. She's about 60 years old and she couldn't figure out that she could just change it to o and ss without complaining about me writing it like that. Then she didn't even know that DE is the country code for Germany. The Ontario office gave me absolutely no lip about the German alphabet or country code, and they were quick and polite. Great post office!
- JCJerry CrossJun 26, 20265.0The guasti post office is the best post office in the valley mostly because not that many people know about it. They have the nicest people and the shortest lines. I've been coming here for 25 years
