I found Oltian's place to be great value for central Athens. It is a compact space, but I did not spend much time in it except to sleep (comfy bed) and shower (hot water). It is a 3-4 minute walk to the coffeshops and restaurants in Psyri and another 10 to Monastiraki or Theseio Stations. This made it very convenient for getting the airport and Piraeus. There is an excellent Taverna a few blocks away (Klimataria). It is on the edge of a wholesaling area and I found the activity of workers loading and unloading vehicles reassuring when walking at night. For the price, I would stay again.
