I would highly recommend Greg's place for your stay in Athens. It has all the major points one looks for when staying in Athens. First of all, the building AND the apartment are both beautiful and spotlessly clean. The location is central without being noisy, walkable to Syntagma Square and also about a 5 minute walk to the "Evagelismos" metro station. Greg was always available and easy to reach and he provided good information prior to arrival. Not only that, but he also had a bottle of wine waiting for us and a few snacks which is always a nice touch and a sign of a true super host! Special thank you to Chandu, his assistant, who was extremely helpful. Overall, we loved our stay and would highly recommend it. Do not hesitate to book Greg's apartment.
