The wahuu apartment was amazing. Koji and Mr. T welcomed us early in the day and helped us settle in. The apartment was really clean and comfortable. Mr. T would come on a daily basis to even replace our towels.
Located in Tateishi it's really easy to get around Tokyo. You just take the Asakusa line and can be in downtown in ~15 minutes. There are lots of restaurants and markets around if you need to go shopping.
Koji would even help us find interesting places to see in Tokyo and help a friend that got a cold during the trip. The hosts are extremely friendly.
I would highly recommend this apartment!
