The apartment is close to the train station (Yamamoto line) that easily takes you to many of Tokyo attractions. Lots of food options nearby in terms of restaurants and grocery stores.
Stayed here with my husband and two little kids (both under 4) and we had plenty of space in apartment. It never felt crowded especially with little ones constantly running around.
We ate at the apartment a lot because it was easier with the kids. The kitchen is not super well-stocked or spacious for cooking (maybe that's judging by my American standards), but good enough to get a meal on the table. With many of the food halls providing prepared bento boxes, it made "cooking" a lot easier too.
Bryan is a terrific host. Response time is fast and useful. Great instructions for finding the apartment and using the appliances too!
