Our stay was amazing. The apartment is gorgeous and conveniently located. We walked everywhere we wanted to go in Athens. It's around 35 mins to get to the Acropolis, a little less to most other things. Taxis/Uber are inexpensive if you'd rather do that, but after all the delicious Greek food you'll probably want the exercise anyway. :)
There are numerous food places very close to the apartment, including a dangerously delicious bakery around the corner.
Thanos was an amazing host! Our flight to Athens got in late and we didn't get to the apartment til around 2am but he was there to greet us and made check in such a pleasant experience! He even had a couple of beers and a few food items in the fridge for us- so gracious!
Everything is pretty self explanatory (except for the hot water for the shower, so ask about that during check in!), but he also has a book that explains everything you'll want to know about the apartment which is awesome. He is also very responsive to messages and is happy to give you any advice you need for your stay in Athens. Really couldn't have asked for a better host or a nicer apartment.
When we return to Athens in the future we will definitely look for availability at this apartment before anywhere else!
