Olga was responsive from day one of booking. Our flight was delayed, but she stayed in constant contact with us and was very accommodating. When we arrived, she was super helpful in explaining how things worked and gave us tips for navigating around Athens. During our stay, she responded to texts almost immediately. The apartment was clean, is cozy, and is located in a great and convenient area. It is in walking distance from shopping, the metro, lots of coffee shops and places to eat. We pretty much walked every where from the apartment, including the Acropolis, Monastiraki Flea Market, Plaka, Syntagma square, and the museums. I highly recommend Olga's place if you are staying in Athens!
