We had a great and comfortable stay here. The location was very convenient for sight seeing, shopping and transferring train lines. Because of its central location, occasionally we could hear people outside late at night, however this was not a major issue for us.
We did not meet Hiro during our stay, but he was always quick to reply to messages and the check in instructions were very easy to follow.
The apartment was quite spacious for Tokyo. It was very clean and had all the amenities we would need, including portable wifi. There were clear instructions and labels on how to use the household amenities. The heating system was great during winter.
Overall a very pleasant stay!
