They did not follow the cancel policy when I called with more than 24 hours in advance. Location is too far away from most lively areas in Tokyo. Ueno station is 15 minutes walk from there, and the closest metro station (2 min walk) requires to make inconvenient transfers to other lines.
The location of the hostel near the station is very convenient for backpackers willing to have easy access to transport (JR Pass users). The staff of the hostel was definitely the best asset, always willing to help and really nice. The kitchen is really convenient and the hostel was clean in all areas.
Really good location and helpful staff. Shinjuku area is two metro stops away. Metro is just 1 min from the hostel. Really convenient for JR Pass users. Shops and restaurants around. Common areas are clean and showers too (100 Y per each 10 minutes shower). Washing machines available. Comfortable capsules. Lockers are a bit small. Your big backpack will not fit!
