My wife and I stayed at Anna's place for three nights and had a wonderful time!
Anna was very responsive and gave us guidance on transportation from the airport. Upon our check-in, we were greeted by her family at their tavern next door. They were super hospitable and their restaurant was so good that we ate their twice during our stay.
The space is very clean and furnished with pretty much every appliance you need. The best part about Anna's place was the location. It's tucked away on one of the quieter streets, but is still central to everything in Old Town. It's only a 10 minute walk to the nearest bus stop which will take you to the airport and many of the beautiful beaches on Crete.
We will definitely be back!
