We stayed here with a group of 10 and have nothing but great things to say! The home itself was very spacious and the rooftop view is awesome. It was also great to have a toilet and shower on each floor (side note: the provided shampoo/conditioner was amazing). We did not feel cramped even with such a large group. The location is perfect and close to a lot of great (late night) food spots & conbinis, Tokyo Skytree, and train stations that allowed us to get around Tokyo easily. Our host was also extremely responsive and friendly.
Overall, we had a wonderful experience here and highly recommend this home for large groups!
