We stayed for 9 nights at Iwanna's apartment. We loved it. The place was clean and comfortable, with an individual style. We loved being able to sit in the living room (which feels a bit like a 6th floor conservatory) and look out over the wonderful view of Athens.
The area felt safe. The walk into central Athens takes 15-20 minutes. There were supermarkets close by.
The flat is well equipped generally with a good shower, washing machine, hairdryer, and iron. The kitchen is just adequately equipped for simple cooking.
Communication with Iwanna was great. She was very accommodating. A definite recommendation.
