Kostis' apartment and Kostis himself were absolutely fabulous. Kostis was easy to communicate with, gave us lots of resources including guide books, maps, etc. and helped us plan out the best places to see and eat. He helped us arrange transportation and was incredibly helpful.
The apartment itself was wonderful. It was spotless, in an amazing location with views of the Acropolis, and within walking distance of tons of restaurants and bars. We loved sitting on the roof deck with a glass of wine! The apartment was fully stocked with tons of fresh fruit, bottled water, coffee, tea, and even toiletries. It was also a plus having a washing machine in the unit that we could use since we had been away for almost a month.
Overall, we had a fantastic stay at Kostis' flat and would highly recommend!
