Mitsuko's place was perfect for a couple days in Tokyo. Very easy to get to from Hatagaya station, comfortable beds, and cold AC. It wouldn't be a great place if you want to spend a lot of time there during the day as it's quite small, but we were out exploring all day every day and it was an excellent spot to rest in the evenings and have a quick breakfast before heading out.
We enjoyed our stay a lot! Thanks Mitsuko!
