Kotaro and Kei's place is in a lovely area of Tokyo near the Nishinippori station. The station is connected to the JR Yamanote line which is great for anyone staying and using a JR Rail Pass. The couple was amazingly accommodating, considerate, friendly, and helped us out whenever they could. Kotaro and Kei are very animated when talking and it's quite a lot of fun conversing with them. Kei's cooking was great when we weren't out eating whatever Tokyo had to offer. The house itself was very nice and well furnished. The room they provided included two different heaters and two heated blankets to make sure we stayed warm in the cold nights. There was plenty of space and a large closet was even provided for our large luggage. I wish we had more time to stay with them in Tokyo. I would definitely recommend this place to anyone visiting Tokyo.
