Yuko's place and the Nakano neighborhood was really nice. It was OK clean and the beds were great. Yuko was also really good on communicating and always answered all questions quickly and politely. Nakano has a lot of great shops and restaurants but if you're into exploring Tokyos nightlife I would recommend staying closer to Shinjuku/Shibuya as the subway stops running around midnight and taxi fares are quite expensive.
But would definitely recommend Yuko's place to a friend - for the cost it's a great place to stay!
