We stayed at Kotaro’s apartment as a family of four including a 7yo and 16yo. The apartment is lovely and spacious (relatively for Japan!) and very clean. The location is excellent being a short walk from Ebisu station on the Yamamoto Line which is excellent for getting around Tokyo. Kotaro also provided fantastic information about the apartment, how to get around, places to eat and areas to visit, and checked in with us a few times during our stay to make sure that everything was ok. The pocket wifi that comes with the apartment is invaluable! There is also a great supermarket nearby. The only thing to be mindful with the apartment is that it is in an area with great restaurants and bars and can get a little noisy at night. We used earplugs when sleeping and this worked a treat. Overall, it was the perfect place to base ourselves in Tokyo for a few days.
