We loved our stay at Kuni's place! This is a very stylish home, with a surprising amount of space for Tokyo. There were 6 of us staying there (5 adults and a child) and there was plenty of room. The hidden nook kept my 4-year old entertained and is such a clever addition.
The location was also great. There is a Family Mart around the corner, and a 7-11 another street over. Kinshicho JR station is under 10 minutes walk away, and there are so many shops around there (Muji, Uniqlo, Loft etc). In the other direction is Skytree which is about 15 minutes walk away. Near Kinshicho metro station there is a great park for kids and a shopping centre with a large supermarket. We were also able to walk to Sensoji shrine in about 35 minutes.
Kuni is a fantastic host, and provided plenty of helpful information. He also helped us to reserve a taxi from the airport which we would have struggled with ourselves.
We would definitely stay here again. Thank you Kuni.
