The Athens Backpackers hostel is OK too. Most of the tourist spots in Athens are walking distance from the hostel.
The room was OK, and there’s also washroom inside the room plus lockers. Sockets are in the corner and dressing table.
They also offered a free breakfast. It’s not all you can 😛
The lift is too small, that it can only fit 1 or 2 person, but with luggage, maybe just 1 person.
You can reserve online and pay your balance at the hostel upon arrival.
