Highly, highly recommend. I stayed for 2 weeks. The second week Athens shut down non essential businesses due to corona. Efthia was a tremendous host and stayed in touch throughout, offering transportation tips and making sure all was well.
As for the apt - it’s centrally located, Surrounded by cafes and restaurants and a 5 min walk to the metro. Clean, comfortable, homey. And has an *amazing* rooftop view of the acropolis.
