My wife and I had 4 nights in Mary's apartment and we can recommend it to anyone looking for accommodation in Tokyo. Shimokitazawa is a wonderful neighborhood full of interesting shops and great places to eat. A short easy train ride to Shibuya and from there to anywhere else you want to visit in Tokyo. The apartment is compact but very functional and comfortable for the 2 of us, well equipped, very clean and an easy walk from the station even with our bulky suitcases.
