Stop looking for other places, this is the place to stay in Athens! I would repeat here without hesitate.
#THE APARTMENT
The apartment is big, well decorated, and has everything you need to make a short or long stay. Internet works for remote calls and work. The kitchen is fully equiped with oven, stove, fridge, freezer, even dishwasher and everything needed to cook and eat. It has also a nespresso machine, a sandwich maker, toast machine, etc... Host even provided extra stuff so I can cook better.
The apartment also has two AC splitters, laundry machine, TV, etc.. It's in a top floor with elevator and it has sun all day long, also has a small interior balcony, in a quiet sunny area, to have some evening wine.
You can see that the host took care of making it confortable leaving delightful touches, they just started renting it now.
It was clean and all required covid material was provided.
#THE HOST
The host was super attentive. He provided from the beginning with a welcome package including bananas, local wine, chocolate and coffee. Also with COVID prevention material.
He was nice to let me do earlier check in and late check out. Was available all the time over whatsapp and even gave me some advices about what beaches visit, how to get there, and what nearby restaurants were advised.
I asked for some extra kitchen stuff and he gave me more than needed.
#THE AREA
It's 3 min away from the subway stop (Line 2) and around ~20 min walking from syntagma square. There is a supermarket that opens from monday to saturday literally down of the apartment (1 min away) and plenty or restaurants, cafes and bakeries in the surrondings. There is a greek restaurant recommended by the host that opens all days and its just 2 min away (try the meat there!).
If you come from the airport, there is a direct train station also 3 min away that allows you to go/come from airport directly. The train passes every hour.
Overall, it was way better than I expected. Thank you!
