I loved my stay here. As a single traveler it was perfect for my needs (though it would also work well for a couple). The flat was thoroughly clean, instructions for arriving and using anything in the apartment (washing machine, air con, etc) were thorough and clear, the bed was sufficiently comfortable to get a good night's sleep, and the host was helpful and quick to respond to messages. The window is at the front end of the side of the building, which I loved because even though the view is the wall of the adjacent building, there's plenty of greenery around the balcony to make it feel very pleasant, and there was still a good amount of natural light. I could also leave the curtains open at night, which was really nice. The location is perfect...easy access to everything Shimo Kitazawa has to offer, close to the train, but it's also quiet. I would absolutely stay here again on a future trip to Tokyo!
