If you're looking for a calm place to stay in Tokyo, Aki's house is a great choice. The house is very clean and neighbourhood is quiet. Aki is friendly and communicates very clearly. She arranged portable wifi for us, and gave us detailed information about catching the train. The rooms are lovely Japanese style, with tatami mats, futons, and sliding screens and walls. This means that noise carries between rooms, but since I travel with good earplugs, that's not an issue for me.
I really enjoyed chatting with Aki, and happily recommend this listing to other travellers. Thanks, Aki!
