Wonderful apartment. I’ll post the key things I care about when reading reviews:
1. Comfortable beds. Nice linen. All very new and clean
2. Good Wi-Fi.
3. Quiet. I heard Gazi could be loud but the apartment block is very quiet
4. Wi-Fi that is new and great in all rooms
5. Self checkin which is useful if arriving on a late flight like we did at 1am
6. Konstantinos is extremely helpful and gives you good tips on where to eat and go. He also arranged the taxi pickup which was seamless. The price is fixed in Greece from the airport so worth booking in advance as they meet you at the gate.
7. Literally nothing I’d change. It’s close to great restaurants, metro and an easy walk to a lot of amazing historical sites. I will stay here for future trips as it’s the best place I’ve found in Athens.
