I liked my staying at Plakias at Alexandros' apartments very much. The host was friendly and very attentive even though he couldn't meet us and we were greeted by his aunt Maria. The Apartment is just how it is portrayed on the photos (even a bit better I'd say) - comfortable, spacious enough for 2 persons, we only used one climate control unit (there are two of them).
Plakias is a very quiet places compared to Rethymno - there are no crowds and only a few people on the beach. Prevelli and Amudi beach are near and available via boat or car.
I would recommend other people staying at Alexandros' apartments.
