Mieca's place was absolutely perfect. First of all, Mieca goes above and beyond as a host. She has included lots of thoughtful amenities for visitors, goes out of her way to communicate and check up on you, and gives very clear directions/instructions. The place is small, but clean and cleverly organized.
Her apartment's location was also amazing. Shimokitazawa is a cool neighborhood with lots of cafes, restaurants, bars, shops, and arcades. Small charming crowded streets and easy to walk everywhere. Literally a 3 minute walk to the train station, and a very quick train ride to the big-city destinations of Shibuya and Shinjuku. Very convenient.
For this price range, I really couldn't have imagined a better location and room. I would even stay here again if I visited Tokyo again.
