Tom's apartment is in an excellent base for enjoying a holiday in Tokyo, being located a 3 minute walk away from the JR Okubo station and a 10-15 minute walk to Shinjuku. The neighborhood is quite lively, featuring a number of convenience stores and great looking restaurants, although depending on the length of your stay, you may find yourself eating elsewhere in Tokyo more often than not.
The apartment itself is fairly small, but very clean and well kept. Everything was quite comfortable and offered a very pleasant atmosphere for relaxing after a long day of hiking around Tokyo. My only small complaint is that the curtains are a touch thin, meaning that unless you're a heavy sleeper, you may find yourself being awaken by daylight at sunrise. Blinders are not a bad investment if you enjoy sleeping in.
Overall, I can recommend Tom's apartment without hesitation.
