In my opinion, this is the best neighborhood in Tokyo. A ton of food, drink, music and more. It is vibrant and busy but at the same time has a distinct neighborhood feel. This is my third time staying in Shimokitazawa and I will be back.
This apartment is right in the middle of Shimokitazawa and a great location. The apartment is clean and has all the amenities that you need. There are two trains that, if you catch the express, will get you to Shibuya in 1 stop and 3 stops to Shinjuku.
Daisuke provides you with a portable Wi-Fi so you will have Internet access when you are out and about in Tokyo. He also has a list of great recommendations for the neighborhood too.
Daisuke is very responsive and helped out immediately whenever I had a question. I highly recommend this apartment and host.
