The flat is lovely, comfy bed, amazing view and Maria is very welcoming.
Little warning, you are on the roof terrace and it’s up 5 flights of stairs with no lift so luggage carrying was interesting. You are also on top of a steep hill so prepare to have strong quads by the end of the trip.
Saying that, Rethymno is beautiful, fun and has great food. The location is perfect as you have quiet but are walking distance to everything.
