We stayed there 5 days out of our 2-week Crete trip, and this place is a definite must :)
Agios Myronas is the most beautiful village we've seen in the whole island. We recommend spending a few hours exploring its ancient narrow streets, steep winding alleys and historical stone houses.
The location is convenient for visiting the central part of Crete, quite near Heraklion, but situated on a hill among olive fields, with stunning mountain views.
The Philoxenia house is old, beautiful, and classy (old stylish furniture) - but also very well equipped (e.g. drinks, sweets etc) and convenient to live in (actually we enjoyed the sheer being there). Also, there is the nicest local restaurant Ethimiko - with lovely local food for good prices :)
Our host was helpful and comunicative and in general, we absolutely recommend this place!
