Thank you cassandra and mikoto
It was a great exprience! Cassandra and mikoto gave a fast response and very easy to communicate with. Place is spacious and in a good location, it is easy to access the bus stop which frequently come and go to shinjuku station (hub of many lines in tokyo). The room is clean, and it is just right as we needed. Nevertheless, i have to carefully operate the microwave as there is a toaster on the top and water heater placed partly next to it + all these stuffs are beside the sink. I think you have more spaces to better put these three ( just like in the photo :)
But overall it was a nice place to stay and i dont have any major problem during my stay :)
