We had such a wonderful time in Athens and Barbara's apartment was perfect. It is in the most beautiful spot, very close to a lovely little shopping/restaurant area and within easy walk of the acropolis.
The apartment is beautiful and spacious, which made a nice change from one room hotel rooms. It also has a roof terrace with views of the acropolis which was a great surprise. And the street it's in is very picturesque.
Barbara herself was extremely helpful (we didn't meet her until we left but talked via email which she was always fry quick to respond to) and we had no trouble at all with anything. Her restaurant recommendations were great, and she even called a taxi driver she trusts to take us back to the airport so that we could have a peaceful trip out of athens and not worry about being charged too much.
Athens was great and if we go again we will definitely stay at Barbara's place, it was just perfect.
