Tomba is a great host. He made sure to provide us with everything we could possibly need. The check-in and the communication was super unproblematic.
His cozy apartment had absolutly everything. And Tomba even prepared lots travel guides and snacks. The beds are really comfortable and had spare pillows and blankets. The apartment itself is slightly outside of Tokyo's center but that's really no big deal at all. You can easily reach it by train and it's just two minutes footwalk away from the station.
We would definitely consider staying at Tomba's place again, if we come to Tokyo again! :)
