We had a really nice stay at Smaragda's apartment, she was great with communication and picked us up from the train station to bring us to the apartment and show us around. She gave us recommendations for what to do in the area and was very receptive whenever we reached out to her. The apartment was perfect, just big enough for two people and has everything one would need, in addition to coffee Smaragda even left us homemade apricot jam. I also really appreciated having the washing machine and drying line which came in handy. The rooftop is amazing as well, we had a nice view of the surrounding area as well as a great sunset view. The metro is about a 10 minute walk and it's easy to hop on and explore other areas of the city. I would definitely stay at Smaragda's again if we return to Athens!
