Mieca's apartment is the perfect base from which to explore Tokyo! Shimo-kitazawa has a more chilled out vibe than the rest of bustling Tokyo, with lots of cafes and small bars and used clothes shops. The apartment is a two minute walk to the station, which is only about five minutes away from both Shibuya and Shinjuku, so you have easy access to the big sights and sounds of the city. I wouldn't stay anywhere else.
The apartment itself is very clean and comfortable and feels very safe and secure. Good for a couple. Mieca was very communicative and we had an easy time checking in and out. Couldn't ask for more! Stay here!
Also - make sure to check out the Okinawa Bar A downstairs - became our local every night and the staff and patrons quickly became our friends :)
