Our family of 4 with 2 teens had a very nice stay. We expected the place to be small from the reviews but it was still comfortable for us. The check in instructions and picture directions worked great! Location is close to 2 train stations and just around corner from convenience stores and places to eat if needed. Tom was super responsive to messages . The apartment was surprisingly quiet- could not hear neighbors at all or much from outside so we got great rest. The pocket wifi worked great! We used washing machine once with no issues.
Only downside for us was the storage space- 4 suitcases and backpacks were hard to fit and still have walking space to move around freely. . Overall a good home base for us to explore Tokyo. A great place to come back to at night to rest for the next day’s adventures. Would recommend for this purpose but maybe not if you plan to spend a lot of time in the apartment.
