Yoshio's place is extremely convenient for accessing the train line that has stops along some of Tokyo's most touristy and popular areas. Ueno and Akihabara are easily reachable, and a lot of the other popular neighbourhoods are on the same line and there are no transfers required.
Yoshio is extremely helpful, very polite, and offers great tips to get the most out of your stay. He picked my friend and me up from the train station, and even provided umbrellas when it was raining. Fantastic host, and would 100% recommend to anyone.
