This flat is ok for the price. The location is very good - you can easily walk to the tourist district/Acropolis. And very easy to find from the airport. Teresia and her sister are clearly really nice girls and the communication was good.
Unfortunately when we stayed there were many broken things - the stove and oven either don't work or are not connected. There is a hot plate available instead but there is NOTHING to cook with. No oil, no spatula, toaster, no pepper, no tea no coffee, no coffee maker etc. We scrambled our eggs with plastic spoons we found in the back of a drawer. The toilet was also broken when we stayed, meaning there was a perpetual puddle of icy water on the bathroom floor. Also the Tv's are very old. The sound seems to be broken on the one in the living room.
In short it is a good location but not a very comfortable flat. But very safe and easy to access.
