i have been at Manolis property 3 nights in September. It 's been a fantastic stay. The flat is very close to the centre of Rethymno and also in a safe area. I went for a tango festival and every night got home very late withouth any issue.
The flat has all kind of equipment: nice gesture the parasol for the beach;). Also nice finding shower gel and shampoo in the bathroom, even the supermarket is just opposite the building.
Manolis also is very helpful and gentle.
i strongly recommend this place if you are planning to go to Rethymno. I will definitely come back!!
