I live near Kifisia! My address in Greece is "Botsari me Xalkidiki 45" I realize this is in Greek and hard to understand if you are not from there but if you need help with anything just let me know! I believe the ambassador hotel is closer to me but either way everything is close by in the city!
There is a bus from Thessaloniki that stops at Fourka. I was going to attach the link but the bus is very confusing online so when you get to Greece I can help you with what time the Bus is at and where you will be leaving from so contact me if you are planning on coming to the pre-wedding party!
