Myself, my partner and our friend made one of our last stops in Japan at Kentaro's apartment, which was really spacious and exactly as per the photos shown. I heard from Kentaro several months in advance and as there were no guests staying on the day we checked in, he kindly let us check in early, which was a great help.
The apartment was fully set up when we arrived, with some welcome snacks and drinks which were very much appreciated. The home wifi and mobile wifi were really handy, the mobile wifi especially useful for when our group split up.
All facilities listed were present. We took advantage of the washing machine and good weather to sort our clothes out and the balcony gave a great view of the Skytree Tower.
The apartment is near to several metro and train stations and is on the main JR Yamanote line, which means you can access most of Tokyo's main districts easily.
We had a great experience and would be more than happy to stay here again.
