We are a couple from UK and were travelling to athens for site seeing and a friends wedding. We hired the whole apartment just for ourselves. As other reviews have mentioned, don’t be put off by the outside of the building, the apartment is stunning inside! Lovely coffee shop on the corner too. We ordered groceries from Wolt which can be collected 2 mins walk away (or delivered!). It was great to be able to do laundry in the apartment - no smelly bag of clothes to take home for us! Good Wi-Fi, air con and the room was super dark good for kids/ naps. One bedroom did suffer from a bit of noise from kids crying in the night next door but we had earplugs which solved that problem.
The apartment can sleep 4, I would say it would be best suited to a couple, a family of 4 but not 2 couples as the bathroom doesn’t have much privacy (the toilet and shower have cubicle style doors just off the living space). We loved our stay here, and how easy it was to get to acropolis but not being in the main tourist trap spot. Would definitely book again!
