I had a really great stay at Satoshi's hostel. I thoroughly recommend it. Satoshi is incredibly kind and really made me feel at home. A great host! He helped with any queries I had and gave me loads of tips and advice on what to see and do in Tokyo. He also speaks very good English!
The hostel is really clean and has very good amenities. It is also in a great location as it is very close to the subway so you can easily get to other parts of the city.
I met some great people at this hostel and if I come back to Tokyo I will certainly stay again.
