As a couple in our 50's, we stayed four nights in a Superior Studio at Rainbow Apartments in early April, which is shoulder season.
The complex is setback from the road by a short, stone entryway and garden. There is space to park, perhaps, two cars directly in front of the gate, while the road around the corner can accommodate everyone else.
In the off-season, at least, the road has virtually no traffic late at night.
The apartment was modern, clean, and quiet. A small safe was in the closet. The bedding was fine. WiFi was fine.
It's a good base for exploring with car Heraklion/Knossos (~20 minutes) and sights east (Malia, Ay Nick, Gournia, Lato, Panagia Kera). The kitchenette had fridge, microwave, stove, cookware, and silverware. You may need your own sponge and dish-soap. The nearest supermarket of any size is 5 minutes away in Malia. However, we bought groceries when passing larger supermarkets closer to Heraklion.
Maria at the front desk speaks English well, and she was very helpful with sightseeing suggestions tailored to our interests.
For example, knowing we would travel later to Rethymno and that we had enjoyed exploring ancient Lato, Maria suggested ancient Elephtherna and its new archaeology museum. (Good advice).
We had no need for the A/C in April; in fact, we used the machine for heating the apartment at night.
When visiting this part of Crete, we would return to Rainbow.
