First of all I have to say that Markos is a great host - he replies fast and couldn‘t be more caring about his guests. Also the location of the apartment is perfect - directly at the beach with a sea view and short ways into the city where all the bars and restaurants are.
However there were some things which I disliked during my stay in the apartment. When I arrived, it was not as clean as I would have expected. There were bread pieces in the kitchen, the refrigerator was not clean, the coffee machine was dirty and the windows were so dirty you could nearly not see through (also grease from people touching the windows before). I think in regards to this there is still some potential.
Nevertheless in general it was a nice stay, if the mentioned aspects are being worked on in the future it would be perfect.
