Hello welcome to Tokyo:)
It's only 1min walk from Minowa-三ノ輪-station(Hibiya Line,日比谷線)
Minowa-三ノ輪-station is just 2stops from Ueno-上野-station(3min by train)
Easy access from Haneda Airport(羽田),Narita Airport(成田).
Nearby;Ueno(上野),Asakusa(浅草),Akihabara(秋葉原),Tokyo skytree(东京晴空塔),and so on.
Great location for exploring Ueno,Asakusa area.
My friend have another room in Asakusa area.If It's full, please have a look at it:)
