We had a great holiday at his place for 8days, really grateful to Naoki-san. He responded to my quetions promptly and flexibly in advance and through our stay. That helped us a lot to travel comfortably . The room was clean and new as we expected and also we could see it rather 'well cleaned'.
The location was quiet and good enough, we could walk to Asakusa area and Skytree easily. It was a little hard to walk from the closest station in a mid of summer though, considering any other opportunities and condisions like here, it was the best option that we could have. really recommended :)
