Having looked at the comments on this site, my girlfriend and I had some concerns before we arrived. Yes it is close to the airport (but this is a benifit as taxis were regular gave us more freedom as we were without a car) But the noise was negligable. As for the beaches a would consider a 10-15 minute walk not far for such a clean and pleasant beach. There were always sunbeds and good facilities near. Should one feel more adventurous the beaches in Lassi are just beautiful, and then just a short walk to some great places to eat.
And finally in regards to Makios, he is a fine fellow with a great sense of humour - should you give him the chance to show it. The pool was always clean and with plenty of room to spread out around it. Good bar prices and offers great advice in regards to getting around a good places to eat.
We had a fantasic time and would not think twice about returning to Erietta Apartments. I could go on but i suspect i have sold it to you already :)
