We had a lovely week in Agia Pelagia. The apartment was spotlessly clean. The hosts were very accommodating, meeting us after midnight when our flight was delayed, and giving great recommendations for places to eat etc.
It's right near a main road for easy access to Heraklion/Chania but is surrounded by beautiful views and there are two great beaches within walking distance.
It might be a squeeze with six adults (four was perfect) but no problem for a family of six. Overall great stay in a really peaceful location.
