My wife and I stayed for four nights at Pygmalion's place in Athens.
The host: Pygmalion was a great host. Very supportive from the beginning with information and answer to various questions of ours. Additionally, he went out of his way when meeting us since we arrived at approx. 5 am the first day! Despite this rather unsual arrival time he has very kind and took time to provide information about the city and suggestions on what we could do.
The place: The apartment is great, very nicely decorated and had everything we needed during our stay. We felt very comfortable there.
Additionally, the location is excellent. About 5 minutes walk to the nearest subway station.
We highly recommend Pygmalion's place to anyone wanting to discover the city of Theseus!
