Numa-san was very responsive and met my needs during my stay. He’s a great host. The apartment is tiny but it has almost everything you need.
I stayed here for 10 days for work and the location is great as it is in the heart of the city. The downside is that it’s extremely noisy at night: traffic, car honks, ambulance siren, drunk people - all happens frequently well past midnight. The apartment is on the second floor so the noise is worse. I couldn’t really sleep the whole time.
Also I’m not sure if it’s reasonable to ask customers to take out garbage. Airbnb is so strange these days.
But Numa-san is nice and tries his best to help. So overall I recommend this place, though you should want to weigh your options.
