If you’re looking for a two bedroom two bathroom place in the heart of Athens you should seriously consider Dio’s place. The apartment offers great privacy and everyone has a space to themselves if so desired as well as a communal hangout area. It makes it so that you can make the dynamic perfectly to what you need.
Location wise you have a great view, and the entire city can be visited from the apartment by foot. From the Acropolis at a five minute walk, to the Houses of Parliament at 15 to the stadium of the first modern Olympic Games at 20.
Dio himself is kind, punctual, knowledgeable of the area, quick to respond, and very much available to you as a guest.
I’d highly recommend staying here.
