In general, the accommodation is great. The room is very clean when I arrived and spacious. The futons provided are very comfortable and clean too. The toilet and shower room are also kept clean.
The place can be a bit hard to find at first but the host gave directions with pictures and I managed to find it with no problems. It takes a little walk from Oimachi station. However, it's a pretty nice stroll as most part of it is through a stretch of park-like green corridor. The station is very convenient for me as I can take various express trains and shinkansen at Shinagawa, which is one stop from Oimachi. The station is also very near to Haneda Airport which is good as I landed there. Oimachi station also has the Rinkai line which makes it very easy for me to go Odaiba.
The host is very friendly that it's quite a waste I couldn't talk with him much (and drink his coffee) due to my very packed schedule. The check in and check out timing is pretty flexible, a definite plus.
Thanks Daisuke for the great stay at your place!
To Pokemon Go players, the surrounding area is filled with Magikarp and Dratini, once in a while Dragonair. Nice place to farm candies of them.
