Nikolaos was super reactive and great in communication from the very beginning, super flexible while i was having administrative troubles coming to Greece and could have canceled. He was very helpful at every step. Getting in to the place was super easy. His appartment is clean, fresh, simple and the fact that there's a terrasse really adds up to the tranquility within Athens. It's right between two great vibrant streets of Koukaki, which is a really quieter to stay, yet filled with awesome terrasses and restaurants. And you find yourself super close to everything, and attractive places to visit in the city. I would definitely recommend to stay at Nikolaos.
