My sister Ronni & I had a great stay at casavathel. Thelma is a very nice host , she tried to give us everything that we need to know as we were 1st time visiting Athens. She also lives the apartment right next door so it's very easy if you need something.
The casa was exactly as described. It was very spacious and clean, sleep up to 3-4 people. Nothing to mention it was very convenient . We took metro everywhere with that costed 1.20-1.40 euros per person for local commute .30-40 mins train from airport (about 12 euros) 10 mins to center. The street was little quiet at night but the neighbor was safe. Locals people were nice as well , there were numerous of time they came to us and asked if we need help when they saw us held a map in our hands.
Enjoy your stay!
