My first time in Athens, so I cannot be helpful in comparing other locations to this one.
In my opinion, the view of the city and the Acropolis is the main reason to choose this place. You can enjoy the view from a large terrace, where you can have breakfast, dinner, or a goodnight drink. The apartment is on the last floor and you enter in directly from the elevator. This is just fun for the kids!
On the same street, there is a nice bakery for breakfast and several cafes.
The metro station is a few hundred meters distant and you can reach every interesting site from there.
We walked to Acropolis, Agora', Plaka, etc.. and it takes around 20-30 minutes. It can be a bit too much at the end of the day for an old person, but as I said the metro can reduce the trip to a 5 min walk (up hill).
The apartment is a large open space without doors, so it can lack privacy if you travel with another couple. It is perfect for a family.
The owner is very very kind and gifted us with a very late checkout.
The area is very safe and quiet.
Therefore I recommend this place.
