Koichi is an amazing host, who went out of his way to pick me and my three friends up from Shinjuku station and take us to his apartment, as well as show us how everything worked! The apartment is huge, for Tokyo standards, and is definitely spacious, even for 4 22 year old women, and would also be perfect for a family! The facilities are great, with everything you could need and more! Thank you Koichi and I can't wait to come back!
