It was great! Host was very nice to us. She gave us pleasant welcome respected our privacy really good, she gave us the keys, told us few simple rules and said if we need anything she is there to help us and she did. Listing description is accurate, beach really is 10 mins by foot, 15 minutes if you walk slowly. Also, tram station is 5-10 min on foot and it takes you to syntagma (main sq.) in 20 min.
Appartement is big and has 2 balconys, one of them is huge and its great to chill on it in the evening. During the day if you get hot, you can just turn on aircondition which is in every room and surf the free wi-fi that is also included. Also, appartement is fully equipped with dishes, potteries some fixing tools and everything you need for doing housejobs like ironing, washing clothes, etc.
Rest of neighbourhood is also really nice, there is mini market 3 minutes away and supermarket 6 minutes away. Also, there is some small river we liked nearby.
Recommendation for Photini, just to get PC there maybe ;)
I would rate this appartement 4,9/5 and would recommend to everyone to take it.
