We had a great stay in Athens. It was a little long of a walk from the metro station when it was so hot with heavy backpacks but we had known that at the beginning. The area was good, felt very safe walking around both at night and the beginning of the day. Ended up walking everywhere - okay even in the heat as long as your prepared.
Nothing but good things about the accommodation, perfect size for two people and the hosts gave great recommendations on things to see nearby especially the restaurant Ama Laxei, very close and good.
For brunch enthusiasts we would also recommend Estrella on Romnis street.
