The good: Almost everything was great. The listing is accurate and deserving of the high rating it receives -- clean, modern, efficient, and an ideal location for exploring Athens.
The bad: Every day of our stay construction in the building started at 8:00 and lasted until approximately 19:00. During that time, a reasonably loud banging and considerable shaking of the building would happen approximately every 10-15 seconds. So, if you're looking to sleep in a little late or perhaps enjoy a siesta, look elsewhere until construction has stopped.
