The provided manual for the house is very accurate. I reached the house easily and exactly as told. The room is very large. There are few convenience stores and supermarkets within walking distance. The house is located near Shim-mikawashima station. Walking further around 10 minutes, you will reach Nishi-Nippori JR Yamanote/Metro station. Some drawbacks would be that the room is quite dusty (may come from the futon). The other one is that the provided pocket wifi speed is very slow. On the day I arrived, its usage was already at 6.6 GB out of 7 GB. I'll just bring my own next time. But overall, the room is worth the price and it just made my trip in Tokyo!
