Athens has a vast selection of hotels and other accomodation types, such as airbnb, hostels. By checking online each particular website is the best option, so you can choose different options.
But when you want to choose an area, where is better? And are there any special places regarding Plaka?
Athens is separated in central Athens, where Acropolis and Plaka is, where the tourist center is.The center includes Gazi- Kerameikos, Lycabettus-Kolonaki, Exarcheia, Pagrati, Koukaki, even Petralona at the south of Philopappou Hill.
Then northern suberbs, where you can access city centre by Line one or 3. Northern suberbs, as the South ones are considered better, which makes them more expensive. The south suberbs are located next to the sea, so they are far more prestigious. Northen suburbs are next to Parnitha and Penteli mountains.
East suberbs are close to center, since Hymmetus mountain distance is really close to Acropolis. East Attica is also where Athens airport is, and there is also access to nice beaches during summer of course. Western suburbs are considered less prestigious, but there are many alternatives for entertainment and nightlife. To the west of Athens there is also the national highway taking you to Corinth and Pelopponesus.
The south could be separated in Piraeus, Faliro -where you can pass to Argosaronikos bay, and the other side, that takes you to Sounio, the southernmost of Attica.
