Kostas is an excellent host even though we did not have a chance to meet him. He was very prompt in his communication with us and very proactive in anticipating what we may need and guide us through. He is a great resource as far as what to do and how to get around the city. His preprinted information about the city is also very useful. The apartment is very nice and tidy with a great view of the Acropolis. The location is in a residential neighborhood and people are really kind and friendly. You get a chance to interact with the locals. Overall a great stay and I highly recommend his place.
