Stayed at Kei's place as a group of seven. Kei and her husband met us at check-in and immediately made us welcome - lovely people. The house is spotlessly clean and had all the amenities we needed. As mentioned by many others the property is set over several floors and the stairs are quite steep and are quite slippery so care needs to be taken.
One of bedrooms has futons, so caters for both those who want a conventional bed and also for the Japanese floor sleeping experience. Either choice was comfortable. The roof level offers a great outside view.
The location is a quiet residential area, but it is so close to all that Asakusa has to offer. We could not have been more happier with our choice.
Thank you Kei, we would love to visit again.
