John (Giannis) and Stella are great hosts. They took good care of us and were very responsive. This was our first trip to Athens and Giannis helped arrange our ground transportation from the airport to the penthouse. He also recommended several lovely local restaurants which we really enjoyed. The penthouse is nicely situated next to the archaeological museum with great views. We enjoyed our walks to all the historical sites Athens has to offer. Thanks again Giannis and Stella.
