We stayed here for 2 nights - and really enjoyed it! The apartment is very modern and nicely decorated, has a big living room, and a cute little balcony (1st floor). Most importantly, it is super well located, just a few blocks from Acropolis. There are some nice bars and cafés nearby, and many more - all in walking distance. We didn't meet Ilias & Danae, but we exchanged messages; they were extremely helpful and gave us great recommendations for restaurants, etc. Super quick replies. They also arranged a driver to pick us up at the ferry port (reliable, 25 euros for about 20/25 min ride). Recommended for a stay in Athens!
