Costa gave us wonderful recommendations when we arrived and responded to inquiries quickly. The lovely flat and it's location were absolutely perfect for our visit to Athens. In the Thissio neighborhood, the flat is on a quiet street but just a block away is the Pedestrian Walk which is lined with vendors, cafes and restaurants. And only a few more steps away, the metro, The Acropolis, Ancient Agora, Hadrian's Library, stores, and Monastiraki Square and Flea Market. Costa also arranged a driver to take us to the airport and mailed my postcards after our departure. A great big thanks to Costa for being an awesome host!
