We had a great time at Sora's place. The kids loved it and we were all very comfortable. We had some trouble finding the place at first, but afterwards the location suited us perfectly, with easy transportation. The only glitch was that the pocket wifi didn't work, but we contacted Sora and the device was immediately replaced. After that, everything was smooth. The apartment was comfy, very well equipped and clean.
Hopefully we can visit Tokyo again soon and stay at Sora's.
