Kumiko took care of all out needs! There was Popsicles and orange juice waiting for us in the fridge in the apartment when we arrived! Kumiko and Koichi provided quick responses to our needs. The light broke in the bathroom and it was fixed within the day! It was nice to have pocket wifi in Tokyo, but the one provided was slow and was not reliable 100% of the time. We got a little lost on the way to the apartment the first time, as it wasn't clear which station we were supposed to get off at, but we found our way! Kumiko and Koichi took excellent care of us, even though we didn't meet them, and we would stay there again in a heart beat!
