Keko is a nice host and her house is a tidy and quiet. Her kitchen are well equipped with refrigerator, microwave, coffee maker, rice cooker....etc. So you can cook what you like at there.
The location is nearby Metro station where is very convenient. And, there is a 24 hours supermarket and noodles shop if you feel hungry at the nighttime.

She is very helpful and will let you know where is good restaurant to eat...

We like her house and will book it if going again Tokyo.
