I had to come to Mito City for my first week of work in Japan. It was close enough to Heart English School, the company I will be working for this year, so overall I liked the hotel for this reason.
Here you will receive very standard Japanese hospitality, if you are planning to go out for the day and come back to check out then this hotel will be great for you, they will hold your luggage for you until you come back; they also have a foot spa outside of the building if that is of any interest to you. :)
My hotel room also had a desk for those busy with much needed paperwork.
The staff were very friendly and pleasant, even going to so far as to escort my luggage into my room when the room was ready. Some negatives: Your room may not be ready as soon as you check in and check in times differ person to person. My room was small, although this was not altogether negative for me personally as I was only there for one night.
Overall I would most recommend this hotel to those businessmen, students or backpackers traveling light.
