Mitsuko was a great host! Me and my friend had problems with the wifi but she came to the apartment herself to help us sort out the problem. Mitsuko provided some useful travel guides which we made good use of. If you haven't properly planned out what you would want to do or see in Tokyo, use the guide books; they are available in English, Chinese and Korean.
The location of the apartment is in a quiet neighbourhood with some restaurants, a convenience store, cafes and a book shop nearby. It is quite convenient for those who would be cooking during their stay as there is also a market nearby. Shibuya, Shinjuku and Harajuku are nearby too.
The only downside to this place is that the bathroom is really small so if you are not bothered by that then, I recommend staying at Mitsuko's apartment.
