Tomomasa’s airbnb apartment is great for spending a night or two in Kōenji. Shinjuku is not far away at all! The apartment provided everything we needed. The beds weren’t as comfortable as I would’ve liked, and the heating units were a little noisy, but these weren’t huge concerns. Tomomasa and AIKO-san were very friendly and their communication was excellent. Also if you’re in the area, I HIGHLY recommend you get some cakes from Black Mountain Cafe. They’re amongst some of the best desserts I’ve had in Japan! Awesome stay, thank you for having us! :)
