Magda's apartment in Athens is a great, cozy place to stay when visiting Greece. My wife and I would definitely recommend the place to couples traveling to Athens. We really enjoyed our stay there.
Magda herself is very friendly, responsive to messages, and helpful with tips for local attractions.
The apartment itself is not huge (bedroom, kitchen, bathroom), but that is exactly what we were looking for. The rooftop patio is huge though, and it offers a spectacular view of the Acropolis. Also, if you are an early riser, it was amazing to watch the sunrise over Athens from the patio.
As far as location is concerned, it is a 5 minute walk away from the closest subway station, and a 10 minute walk to the historic old town (Plaka). I really enjoyed both the location and the rooftop patio, which makes this apartment a great value for the price.
