U of Iowa is highly over rated. Choose wisely before choosing here. I go here and in my opinion the facilities are outdated, the school is poorly administrated and the professors do not really care.
Make sure to ask about the crime rate.
Parking is horrible.
Shop around!!!
To be fair, you've only had 1 semester so far, so how can you make blanket statements that the professors don't care when you've only had a few? Yes, some are bad and a little arrogant, but others are amazing. The same can be said for just about any school out there. The building is older, but you already knew that before you came here (tours are provided at the interview) so you can't really complain about it - you chose it. The practice lab is pretty up to date, though, and that matters more than how old the desk you sit in for lecture is.
To me, parking isn't bad at all. If you expect there to be an abundance of free parking, that's probably where your problem lies. There are parking garages all over the place, along with the metered parking. Either fork out the money for the garages and meters, get a bus pass, or get a permit for the student lots. Don't expect anything for free.
In response to your earlier statement about it being cold and miserable...it's Iowa and it's January. What did you expect? Beaches, sunshine, and palm trees? This winter has actually been pretty mild compared to the last 2 years, by far. But, for those who don't like snow, you probably wouldn't like it here much, at least not during the winter, so be forewarned.
To everyone else, just make the most of your interview visit. Take the time to look around and ask lots of questions. Get the answers you need to make an informed decision for yourself and what you think is the best option for you. Whether it's here or somewhere else, good luck to you!
