Our stay at Greg's place was outstanding. He was an excellent host; providing a bottle of wine, some snacks in the fridge and a stellar mini guide (that he wrote) on Athens and the area. We checked out some of his recommendations and were amazed! He knows Athens well and has excellent taste (literally and figuratively ;)). The apartment was also extremely clean and nicely arranged. All in all, a great stay. We stayed elsewhere for our last few nights (booked it first) and it was subpar compared to Greg's place. Highly recommend this accommodation!
