Ice was there upon our late arrival (22:30) and because we couldn't find the house (it is partially located where cars don't have access), she took her bike to look for us.
It is a very nice house with a lot of beds. We stayed with 3 kids (aged 12, 9 and 7) and took the two bedrooms upstairs. It was sparkling clean, there was breakfast provided in a large basket and the fridge filled with bottles of juices and drinks, that was very nice. The only thing we would recommend is to place curtains in front of the large windows in the bedrooms, because we woke up very early with the sunshine.
The location is great, there are many convenience shops on the main street and the subway lines are 5-10 minutes walking.
Would we come back to Tokyo, we would definitely stay at the same place, and in the meantime, we duly recommend it to other travellers.
