The space is bigger than appears in the pictures. Nice and clean, and the area is safe (helps the police station is 5min walk), 7/11 is super close too. We loved our stay here, everything is super straight forward and host replied fast when you have questions.
The place is about 20min train ride to Takadanobaba where you can transfer to the train that will take you to Shibuya etc.
10/10 recommended. :)
