The check in process was very easy with clear instructions of how to arrive from the closest metro station and where to get the keys. The house is a walk/one metro stop away from Shinjuku and has enough space to accommodate easily 5-6 people. There's nothing "luxurious" but the quality-price is really good. I would say that the house needs "a bit of love" to make it more comfortable and nice but overall we had a very nice stay
