For the money and value, this is what I expected. the apartment is fair size, some people may find it is little old but I find it just fine. Clean, neat and tidy, AC works as expected, all things you need are provided, even umbrella, which prefect that visitor don't bring with them while travle. On top of that Sayaka provided pocket wifi which is a life saver when you go out. Location is very convenient, close to convenient stores, restaurants, supermarket, Shinjuku shopping area and subway stations.
I enjoyed my stay and recommend for others looking for the same.
