If you want to visit Crete, you have to stay in this apartment, really, just add it to your todo list as a first point
1. Stay at Maria's apartment,
2. Visit Knossos,
3. ...
Why ? Because Maria is one of the best persons on this planet. Really. Apartment were very comfortable and clean. It's located not far from bus station, and not far from the beach. Best place to stay for a best price. I'll be glad to stay there again and again.
