We were there three: my wife, my daughter, and me. It was our first visit in Athens.
This apartment is located best for tourists. From there you can find the best way anywhere in Athens. On the street Valtetsiou there are many very good and really cheap restaurants. Sometimes it can be little bit noisy in this area but it's acceptable for the city center.
The apartment was VERY clean. There was everything you need for a short stay (1-2 weeks) in such a big city.
All windows go to a very small closed yard and you really have nothing to see there. But we had no time to look outside the windows. We saw many good things by walking in the city. So this is not a disadvantage for such active tourists like us. And the price was really low. The Host Georgios was always ready to help. Many thanks to him!
So I recommend! Rent and enjoy!
