We were in the 3LDK and the entire team made it their mission to make sure everything was perfect for our 5 days in Tokyo.
Shinjuku area is thriving w lots of Izakayas and good restaurants and we had no trouble getting on the metro ( bought the 72 hr pass) and swing across Tokyo from one end to other from the Higashi-shinjuku station.
The view from the balcony of the docomo tower is fun and getting your own blue sky to look at is worth the price from the lovely sitting room w Japanese architecture and tatami mats.
The kitchen was well equipped and we did not have any issues though we mostly ate out but did make tea at home.
It’s advertised and setup for lot more people than just the three of us but we enjoyed the extra space we got. Note that the apartment has one toilet and one shower - so for three of us it was not a problem at all but bigger groups should consider this.
We will definitely revisit on our next trip and make it a home base.
Thank you Sumifoku team!
