The apartment is great. Don't let the slightly underwhelming street entrance mislead you, once you have taken the lift to the 6th floor and entered the apartment it is very different. The apartment is lovely, smart, well equipped, comfortable and immaculately clean. The bed is comfortable (We didn't use the 2nd bedroom) and the balcony above the street is makes a nice outdoor space. Worth saying the air conditioning is highly effective, very quiet and much appreciated.
Our son, who lives in Athens recommended the Pagrati area where the apartment is, and it is a good choice with easy access to the city centre and a nice safe feel.
Definitely highly recommended and I would happily choose it again.
