If you are going to visit Rethymno, I highly recommend this place. It has a very good location in the city: very close to the bus station, about 15 minutes by walking on the wonderful streets to the main beach of Rethymno, there are lot of grocery stores and restaurants near to this flat.
Additionally I want to note a very good service and very nice owner of this flat.
In general: only advantages and no disadvantages, highly recommended!
