Just awesome. Great location, great apartment and host. My wife and I had easy walks everywhere, good grocery store two blocks away along with numerous bakeries, pharmacies, etc. Quiet too. Quick, casual walk to the acropolis, museums and other ruins. We only took public transportation to/from the airport which was easy using station Fix.
We stayed 5 days - great communication with Tzeli prior and upon arrival. I've had nothing but great experiences w/airbnb in istanbul, Paris, austin, and elsewhere, but my wife and I agree this was the best.
If anyone wants any dinner recommendations, feel free to write my account.
