The communication was good and Hatagaya is my favourite neighbourhood in Tokyo. You will go by foot to a range of nice cafes and restaurants. Theoretically you can even walk home after a night out in Shibuya. There are some downsides to the apartment however, the amenities are quite aged so it is very basic. Also the bar downstairs is not that much of an issue, but across the street (2 meters window to window) there are a few bars that are usually running all night with karaoke, so it is unfortunately always noisy. Doesn't matter much for a shorter stay I think but if you stay a bit longer as I did it takes a toll on you.
