The accommodation has pros and cons.
The location is great, very close to Syntagma Square and convenient for walking to the Acropolis and the districts of Plaka and Monastiraki. The apartment is a bit dated and the shower has no curtain so the bathroom gets flooded easily, but the air conditioning works well, essential to survive the Athenian summer. In short, a somewhat shabby apartment but in a fantastic location.
The problem is cleanliness. The sofa cover is so dirty that we couldn't sit down. The sheets, pillows and blankets are dirty too and often full of someone else's hair.
The price is cheap, it is true, but I would really recommend more attention to hygiene. And I would ask the host to be a little more prompt in responding. All things considered, an acceptable solution for a few days if you want to save money and don't have a lot of expectations.
