Extremely nice location, main train line just close by but still very nice and quite neighborhood. We even had a Sakura full blossom in front of our window!
Nice apartment with an excellent space for Japan, all you need in terms of electronic devices, even a pocket WiFi that you can take with you during the day, which is very helpful.
Hope to stay here again next time in Japan.
Very fast answer and whatever questions we had the Zen team helped us with.
Highly recommended!
