Amazingly clean and stylish penthouse in the heart of Tokyo. Very flexible and helpful host. Great access by two subways lines nearby. Lots of restaurants in the neighborhood. A famous cherry blossom place called Chidorigafuchi is just within 5 min walk.
The downside, if I have to pick up one, is the oily smell in the entrance corridor from the Chinese restaurant in the building. Smokers outside the entrance were another headache once in a while (they seem to be kicked out of the large building next door).
Having said that however, the apartment and the management was awesome. Highly recommended.
