We didn't meet Eracle personally, he wasn't in Rome, but he was always available by phone/email/sms/airbnb service. All questions I asked were replied within few minutes.
In spite we arrived at the apartment in very late hours, Eracle's representative comes to meet us, he explains everything about apartment and says that we can call him regarding all questions we have.
The apartment was very clean (looks exact like on the images, even better) with all accessories you can imagine.

I hope next time in Rome will use Eracles apartment.

Thanks a lot.
