Never got to meet stefanos but he's very prompt with questions through the Airbnb platform. Check in/out was a breeze. To be honest we were very scared after reading the recent review about safety. It's in an office building and looks kinda shady from the outside, but the studio itself was well equipped and very comfortable. We were just a bit concern about safety. Anyway, our neighbor (also stefanos' guests) were very noisy but other than that, we didn't have any issues.
