Had a great time in Shimokitazawa - really good location especially if you are interested in more unusual shopping and vintage stores. There are also great restaurants. The apartment is literally 2 minutes from the station with very convenient connections to other parts of the city (Tokyo public transport is a dream - I recommend getting a Pasmo card to make it even easier). The apartment is exactly as described - small but with everything you need for a comfortable crash pad in Tokyo (including a superb welcome basket with snacks and drinks - thank you so much!). Daisuke takes hosting very seriously and was constantly in touch to make sure i was having a good time and was able to advise on absolutely everything - he has detailed blog posts on almost anything you could possibly wish to know about the neighbourhood and the rest of the city.
