We would stay at Katerina's place again on our next stay in Athens in a heartbeat. The extra amenities she provides such as stocking the refrigerator with breakfast items, and providing a bottle of wine were very nice. The studio apt is located on a safe commercial street with clothing stores and small eateries. But even though the restaurants were still 1/2 full at 3:30am on the weekend, there wasn't any music playing so it wasn't noisy. All the sights you would want to see in central Athens are within walking distance. But the best feature is the balcony, where after the crowds and bustling of Plaka it is a nice quiet haven with a great view of the Pantheon.
