Alexander's place is definitely the place to be if you are in Athens. It is walking distance to all the major sites and is very central.
I had requested for an airport transfer as I had my parents with me. Alexander had made this very smooth for us by arranging for someone to pick us up right on time and very friendly. So please take advantage of this offer if you can.
The place was very spacious, clean and comfortable. It had all the necessaties one would need. The building was equipped with an elevator which was very helpful for my parents and luggage.
If you are looking for a place to eat, the restaurants right across are really amazing.
Overall a great experience and would definitely stay at Alexander's place when I visit Athens again.
