Konstantinos allowed us to drop our bags off before we checked-in. He was easy to get a hold of before our stay and during it. The Airbnb itself was nice along with the convenience of an elevator/lift to get to the sixth floor. The Airbnb is on the 7th floor though FYI. We enjoyed being on the terrace to look at the Parthenon at night! The Airbnb is really close to the Monastiraki square and metro station.
