Staying with Sachiko and Klara was lovely and calm, it was nice to live in an area away from the hustle and bustle. The walk to the train is about 12 minutes, depending on your pace, but a very straightforward one once you know the directions. There are a number of convenience stores open 24/7 on the route, as well as a Mos Burger by the station, which I very much recommend. Taking the express train will get you to Shinjuku in about 40min (including a single change at Takadanobaba, where you can pause for some Starbucks on the way to the other train line - try the yuzu tea). While Sachiko has her hands full with work, she will always try to find time to chat with you, and answer any questions she can. There are three guest rooms, so you might have a few new people to meet, as Sachiko gets guests from all over the world. Even so, if you're a person who likes to keep to themselves, you won't be intruded upon!
