Alexandra has a very nice, clean and charming apartment in an interesting part of Athens, with some good bars and restaurants within a 5-10 minute walk. For the main Athens sites it's either a 35-40 minute walk or you'll need to take public transport.
Alexandra herself is a very kind and friendly person. Communication with her before our stay and her directions to the apartment were excellent.
We enjoyed our stay with her, as I'm sure anyone would.
