I recently stayed at Kevin Fuku’s place in Hatsudai, Tokyo with 3 others.
PROS: great communication with Kevin, he provides detailed instructions with pictures on how to get to the house and the rules. Even though he never makes an appearance, he answers timely via email and text for any questions/concerns. Place is very clean and well kept. Two full sized beds were comfortable and decent space for 4 people. Comforter was thick and comfy. Bathroom was very clean, provided shampoo conditioner and body wash. There’s hot water with good pressure. Kitchen was clean with basic appliances and mugs. There is pocket WiFi provided. Up the road there’s a convenient 7/11, awesome bakery, restaurant with bento boxes, ramen place, seafood place, and breakfast cafe. It’s a 7 minute walk from Hatsudai train station, which has a local line that can take you to Shinjuku train station to all the other JR trains. Roads and neighborhood are very quiet and peaceful.
CONS: very strict with rules about being quiet. House is kind of a long walk to train station even though it’s only 7 minutes, it’s hard with luggage. Space is cramped for 4 people, will be best with 2-3 people. Bathroom and kitchen are very small.
