Tatsuro san was a great host. I believe I was the first Japanese to stay at his apartment. However, he still gave me a very detailed information on how to get to his apartment and I got there without any problems. It was easy and was actually quite close to the railway station. The room was very cosy and had everything I needed to stay for two weeks. Location was really nice. Had everything from supermarkets, bookstore, a dollar store to a laundry in a short walking distance.
There were lots of places to eat as well. So, even if you don't cook, you won't starve! Actually, the Taiwanese restaurant right next door was quite good.
Tatsuro san was very considerate and even offered me the lower floor room so that I do not have to carry my luggage up to the 4th floor which was initially　assigned to me.
I would wholeheartedly recommend this place to anybody who wants to have a quiet and convenient stay in Tokyo. Of course, not the luxury of a nice hotel, but it provides all the basic needs and comfortable bed at a decent cost.
