The apartment is just as seen in the pictures, cozy and clean. Panos was an amazing host, very friendly and accommodating. We made use of the parking space provided because we drove to Athens but we also used the metro/subway a lot since the closest station was only about 5-7 minutes away on foot.
The only thing I would advise is that, if you are a light sleeper, choose the second bedroom. It might not have amazing night views of the acropolis like the other one, but it faces the back of the building and away from the noisy street so it is more quiet at night.
