Had a lovely time at Ko's! The apartment is stylish- It gives the feeling of a bigger space due to the loft bed at the top, which is hard to find in Tokyo. It's in a quieter part of Shibuya- Not in the *heart* of all the crazy, but about a 15 minute walk from the scramble. It's a super nice escape but also close enough to make it easy to get to the fun.
Highly recommend! Ko is very communicative and kind too.
