Mixed results
Good: I was able to find what seemed like a good parking deal while visiting Chicago. The spot was cheaper than parking offered at my hotel and was only a block away.
Bad: instructions were not clear. I ended up pulling into a parking garage across the street from where the valet was waiting and had to pay an extra $16 for my mistake. When I called Spot Hero, the person who spoke to me was dismissive and insinuated I did not know how to read.
Conclusion: Good app, bad UX, worse customer service.
