Hiro was a friendly, very responsive host. However, this stay ended up being a bad experience for 3 issues below. I don't think they were intentional, but the overall experience ended up inconvenient for international traveling.
1) My original booking near Asakusa was double booked, so we had to switch to the Kagurazaka listing last minute. It's a bigger place and Hiro kept the price the same.
2) The building elevator was broken. So I had to carry two large suitcases up to the 5th floor manually, which was extremely inconvenient. It was not fixed during the four days of my stay.
3) Bad Wi-Fi connection with huge latency. The wifi often disconnected and I could not use for video calling and remote work. Tried turning off the breaker but didn’t help.
Hiro did offer a partial refund in the end. Without the issues I think it's a good place, but I ended up spending a lot of energy trying to fix the issues during my stay.
