This is a great place in a funky neighbourhood. Lots of laneways with cafes and casual restaurants. A short, flat walk to Monastiraki Square, the Ancient Agora (buy your combined ruins ticket here before you go to the Acropolis so you can skip the very long Acropolis ticket queue) and the "flea market" (which is mostly standard shops full of leather and tourist wares these days).
The view of the Acropolis and other monuments is great. Like all of Athens, the streets feel a bit grimy and the view from the apartment overlooks a number of run-down abandoned buildings (although the place across the road has been renovated on the ground floor, the upper floors are still boarded up, yet to be renovated).
The photos of the apartment and view are accurate and the apartment is clean and comfortable.
I really appreciated: the large cold bottle of water in the fridge on arrival, the multiple coffee options in the kitchen, the tips from the hosts on local spots to eat, the taxi trips to and from the airport that they arranged for me, the free laundry facilities including laundry powder and the instant responses when I had a question.
(The curtains and blinds in the apartment don't cover all of the windows completely so bring a sleep mask if you need a dark environment for good sleep.)
