We stayed overnight at Akiko's place. We were just in and out but the stay was pretty good.
The room was quiet and clean. The common areas were a bit cluttered and the lock on the bathroom door was broken but those areas were also clean.
Akiko is very responsive and nice. She has a very cute dog in the house. The dog is friendly but a little mischievous. He ran off with one of our shoes and it took a good 20 minutes out of our morning trying to find it. The dog also playfully nips, which is cute at first but gets old.
Overall, a comfortable place in a good quiet area of SM.
