Our family of 5 had a pleasant stay at DoMo's place.
Location - excellent. We couldn't have asked for a better place. Super close to the Shin-Okubo train station. The stop is also one of the Yamanote line - this makes getting around Tokyo very easy. But as the other reviewer mentioned - there was no escalator nor elevator at this station, so it was a slight inconvenience to get the luggage up and down the steps. We were relieved to see elevator at the apartment unit! The main street is busy and has lots of places to eat starting from breakfast to late-night snacks. Multiple convenient stores along the street.
Check-in - very easy. DoMo sent us a clear email and step-by-step instruction on how to get into the unit.
The unit - it was small, but very functional in Japanese standard. I am picky with the cleanness of the bathroom, this unit was impressive. Overall a very modern unit and appeared new and well-maintained. The apartment unit was very quiet even though it is close to the main busy street. It does have a washing machine, but no electric/gas dryer machine as we do in the U.S. There is a bathroom fan setting for drying your clothes, it worked ok. We did manage to wash the essentials.
The complimentary breakfast at the DoMo cafe was very nice as well. Thank you!
We would definitely come back again if we visit Japan in the future.
