Highly recommended place to stay!!
We (2 people) stayed 2 weeks and it's in a great location for Tokyo. Neighbourhood is very quiet and friendly. Apartment is small/medium for Tokyo but very well planned out. Stairs are steep to second floor so not ideal for everyone. Apartment is very clean and had lots of nice touches to make a pleasant home.
Keijiro & Mao we're excellent hosts, responding really quickly and helping out in any way they could.
No doubt would stay again.
