The place was accurately described by Hajime. Since we are a group of 10, the living area and kitchen was too tight for us but the rooms were comfortable enough for all of us to get rested daily. Although we wished there were more pillows for us to use. And the other shower room was too small for some of our companions. But we loved that a free pocket wifi came with our stay and it was a close walk from the Keisei Koiwa station. Since we had our senior parents with us, one transfer each time to the attractions became a little inconvenient for them.
But overall, our stay there was comfortable and Hajime was always responsive.
