Giannis is a great host, hospitable, kind, polite, all the words you can use to describe a good human being. He is also knowledgeable about Greek history, you will benefit from that for your trip. His place is clean and artistic, located in the center of the center, just at the foot of the Acropolis, perfect base to explore the city. I had a wonderful time here. Highly recommended to anyone who visits Athens!
