My group of 5 stayed at this home and it was an amazing value for us. The place can house many more people (I would say 9 very comfortably and a few more than that if you're willing to share smaller beds). So with just 5 people we each basically had our own rooms. The directions that were left for getting to the house were invaluable. We had no issues getting off the train and following the step by step guide.
As far as the location goes, the house is a short walk to several train stations and about 20-25 minute walk to the heart of Shinjuku (which is our favorite area in Tokyo!). It was perfect for what we were looking for. The home itself is in a quiet neighborhood so don't expect to be able to have raging parties at the house. It's also super convenient to pop out for some food or shopping at the nearby Lawson, 7-11, McDonald's and Don Quixote.
The house itself was clean, the beds were nice, and we had all the amenities we could possibly need. The host was very responsive and very helpful. Overall, we had a fantastic experience and would recommend this place to anybody. We feel there was a lot of value in the cost, given the location and the size of the house. Thanks again to our wonderful host!
