The apartment is very well located in central Athens. You can walk almost anywhere to see the various historic sites.
The highlight of the apartment for us was the very large outdoor terrace. As the apartment is on the fifth floor, you get a great view of the surrounding area. Great for breakfast or an evening cocktail.
Our host Athanasios greeted us on arrival and even brought us some water, orange juice and milk!!! A nice touch after a long flight.
The apartment has a nice kitchen with everything you need. I suspect that each visitor leaves a few things behind. Whether it's salt/pepper, ketchup, a bottle of water, tea, etc. I'd recommend checking out the fridge and cupboards should you need anything of that sort.
Finally, one "caution". We had a 6:00 am flight and left the apartment at 4:00 am. As requested, we left our keys upstairs in the apartment, including the key to the front door. When we got downstairs, we could not get out as one of the residents had locked the deadbolt on the door with the key and you need a key to unlock it. We called Athanasios and he came right away to let us out. So ... Before you leave, check to see that the door downstairs to the outside is not deadbolted shut.
Bottom Line: Great apartment, beautiful terrace, nice view, very clean with and an excellent host.
No hesitation to recommend this apartment to you.
Enjoy Athens and watch your pockets. We got pick pocketed on the Metro. :(
