We stayed at Aki's for a full week.
Her house is located in a lovely and quiet residential area, where you will find shops and nice bars and restaurants.
The house is a typical Japanese house, with beautiful rooms well decorated. Depending on your luck with other guests, it might be slightly noisy at times but we had no specific issue during our stay.
The room was very clean and well prepared, as well as the bathroom. Tea, coffee and Japanese sweets were provided as well. Aki offers additonal services that makes your stay better than in many hotels.

She is a great host, constantly taking care of her guests and proposing help. She will make recommendations for your time in Tokyo and she is very approachable.
We really recommend staying at Aki's!!
