Sei's place was very easy to get to with the directions and pictures she provided. It is about a 10-15 mins walk for Jujo station which is a JR station, so if you've got a JR pass you'll be a pretty set. The place is kind of small with just enough room for 4 adults and luggage. But for 4 adults it was very cozy. The beds and blankets were very comfortable so if you're just planning to have a place to just sleep while you travel around Tokyo I recommend trying this place out. The heating system for taking a hot shower is dated but Sei's instructions are quite clear and easy to understand so it wasn't a problem to get started for my 3 friends and I. The portable WiFi she provided worked most of the time but make sure you bring a power bank / portable battery if you're planning on going out all day or the WiFi battery will die out. Overall this place was great and I would stay here again.
