Ken and Mayu's place is great! There are lovely artistic touches everywhere. Communication was excellent, check in was easy and the house manual was very helpful. The Wifi worked well also. The space was cozy and fit 2 adults comfortably, especially with a king sized bed.
The neighborhood was perfect as it is nice and quiet but there are many restaurants, shops and attractions to walk to. It's also a quick walk to the train or bus station to explore other parts of the city.
I would definitely recommend Ken and Mayu's place and would be happy to stay there again if I am ever back in Tokyo.
