Not the kind of thing you'd predict yourself saying, but I'm a fan of Mail Plus!
We needed a U-Haul and this happened to be the most convenient location with availability. Pickup and dropoff were quick and easy. My only minor issue is that the options I selected online didn't appear to transfer to them. Then again, it seemed like they were training a new guy on the system and maybe he wasn't familiar with it. They have 24-hour dropoff, but we finished earlier than expected and they were still open.
Overall, it was just a positive experience. The girl was super friendly. The store reminds me of a Mom and Pop Asian store except their goods are Eastern European. We asked for some recommendations and picked up a few chocolates. We also picked out a couple of non-English-labeled Orangina bottles because, according to the girl, they have regular sugar instead of high fructose corn syrup. But then we picked up some Orangina from Trader Joe's the next day and I couldn't tell the difference.
Anyway, I'll definitely keep this place in mind for future U-Haul rentals. Or random Eastern European meats and chocolate.
