I never met personally Sandy but since the beginning she was very communicative, payng attention for every details .
The flat was exactly as I imagined , very clean and tidi , everything you need for a short stay , in a little space but very welll organized .
find the place and the access was very easy thanks to the instructions tha Sandy gave us. Also the position is greact : very closed the sea, just behind Aristotele square and few minutes wallking from yhe White Tower and others nice places.
The only issue (quite important ) was about lack of water during the last night, the communication was great, apparently was reagarding the whole building.
She answered immediatly and apologize about the incovenience, tryng to sort out, but we left the flat in the morning so I don't know anything else.
However execpt this we had great time in Thessaloniki!
