The hotel is very nice (and so is most hotels in Japan).
I walked pass it several times before I found it. It's on the left hand side of the main street, not in a side street like it was indicated on their map (or shown on the Google map). It was next to a parking lot. Walking towards Asakusa, before the first traffic light (from Inaricho station east), you will see a little alley on your left. The Oak Hotel sign is on your right hand side on the side walk, not very visible at night. It is just a simple wooden board.
