Yannis and Helene were the most helpful and attentive hosts you could imagine! Despite never actually getting the chance to meet them in person, their constant attention to our needs and questions made us feel comfortable in a foreign city, we've never visited before. The apartment has all you need, and the location is in a besutiful quiet neighborhood, with everything in walking distance!
We would recommend staying at Yannis & Helene to any friends and family, and we will definitely be staying here next time visiting Athens! :)
