Shibuya Star 1 is a really great place to stay, its close to Shinjuku area.
I came with my family of 7 ppl and its a great place to stay.The surrounding is nice and quite. When you walk to the main street, you can find lots of 7 Eleven, Lawson, Family Mart stores and many places to eat. There's also a big supermarket near the Shinjuku Park as well.
The host, Fu-Chen himself is very responsive and helpful. When I ask something, he always reply soon (within 1 hour), even when he is busy, he will notify us that he was at a meeting or driving and reply soonest.
The house has 4 floors. 1st floor to put your shoes and change into slippers (all provided). Then 2nd floor there's a kitchen and dining area and a room with 2 beds, plus 2 toilets and a bathroom. On 3rd floor there's a bigger area with 5 beds, a dining area, small kitchen, 2 toilets and a shower. The last floor is washing machine & balcony.
I highly recommend this place to stay, especially for large group of family or friend
