Just back from a Europe trip. Got a chance to stay at Xenia and Valerian's place for only one day.
I would start right from the beginning. 2 days prior to the stay, Valerian proactively contacted us and shared a detailed route plan to reach from the Airport to his place.
As discussed between both of us Valerian waited for us to arrive and handed over the keys. He also was extremely patient to listen to our questions and gave us a detailed plan on how to roam around Athens. He also helped us with a Map.
Valerian js an extemely courteous boy and sweet too. He left us two bottles of juice and two packs of chocolate as welcome gift.
The most important part of the stay is Valerian's home. What a sweet home it is!!! It is a small studio apartment which has every damn thing that you could ask for. I loved the stay and would come back again.
