I chose to stay with Alexandra because of the location and because of the wonderful reviews of her as a host. I was not disappointed. A five minute walk and you find yourself hiking up Lycabettis hill, which is the best place in the city to watch the light of the sunrise wash over the Acropolis.
Alexandra is super nice and very welcoming. She made me feel welcome to the entire place. Definitely eat at the Creten restaurant in the neighborhood while you are there.
