Everything was fine except for parking. Based on his description, street parking is free, especially around the King Apartments (Highland and King Ave). But the roads were not free between 8am and 10pm based on the road signs.
He also responded to my question, "If you're worried you can pay for permit, it's up to you, but they don't enforce it at this time on a Saturday. They are mostly enforcing during the week when OSU students are parking going to class." His mention is also indicating that it is no free parking even though the city typically (conventionally) does not enforce it. So, I needed to pay for the street parking.
He should correct the description "It is free only between 10pm and 8am."
