We spent 3 nights in Stella's place and had a great time. We were met by Stella's husband who showed us around the apartment and its amenities, and helped us bring the rental car into their front space. It is a very comfortable apartment on the 2nd floor (through a locked main entryway) and has balconies on the front and back, including a drying rack. We ended up using the washer for a few loads and hung everything outside comfortably. The location is excellent, in a quieter part of town but within walking distance to the city center. Stella and her previous guests have left guidebooks and maps to help you plan your adventures (we drove to Phaestos and recommend it), and one of the stops for the hop-on/off bus is close by (€15/person valid for 2 days, we took it to Knossos and the Saturday street market).
If you have a rental car, I would definitely recommend parking your car outside of the main ring road and walking in...we ended up almost getting stuck on a narrow one-way street after mis-navigating! Their parking space is small and a bit difficult to access, especially with pedestrians and other motorists catching your attention.
