Dimitris' apartment was a wonderful home for my stay in Athens. Everything was super easy with the check in, and the apartment was perfect for my needs as a solo traveller. It was very clean, well-kept and I really liked having a little balcony for my morning coffee.
The location was perfect for the exploring I had planned - both walking to nearby neighborhoods and to the Acropolis, or to get the metro from Omonia.
The only thing to note is that this street and the immediate area is a little bit rough - fine for someone like me and really not a huge issue, but I can imagine that other solo travelers or families may be a bit uncomfortable with the immediate area.
