I stayed at Ko's wonderful apartment for 5 days, and had a wonderful time.

The apartment is beautifully designed, and exactly as pictured. For the price you're paying, you're getting A LOT of space for an apartment in Tokyo. The fact that I actually have to walk more than 5 steps between the bath tub to the toilet? Unprecedented! Given that most Japanese apartment bathrooms have the toilet right next to the tub.

Ko was gracious and patient in explaining everything in the apartment.

The only negatives that I would have is the fact that Nishi-ogikubo is a bit farther away from the downtown area of Tokyo. This was not a problem for me because I've been to the Shinjuku/Shibuya areas plenty of times and was happy to explore the area near the apartment. CARROT restaurant nearby serves EXCELLENT steak, if anyone is interested.

The apartment is also right smack next to the train station. This is great for commuting, but for the noise-sensitive people, this might be a small issue. Ko gave me ear plugs to kope with them, and generally trains stop running after midnight, so it didn't bother me that much.

But if you can overlook these minor inconveniences, you'll be staying in a clean, comfortable, beautiful space that was obviously designed with a lot of thought, by somebody who cares about design.
