My friend and I stayed at Hotel Route-Inn before a test the next day.
The room was your basic Japanese hotel which is on the smaller size, but we were only staying for 1 night so it wasn't an issue.
I guess I didn't read the hotel description as well as I thought, so I was pleasantly surprised by the onsen and the complimentary breakfast. Both were fantastic, although the women's bath could only fit 4-6 people.
The parking lot was big and could fit a lot of cars, but the stalls were pretty narrow.
The hotel isn't THAT close to any train stations, so I don't really recommend staying here unless you have a car.
But there's a convenience store right across from the hotel, along with a Sega Game Arcade~
Anyway, I would totally stay at Hotel Route-Inn Hirosaki-Joto and other Hotel Route-Inn locations again!
