Nicholas's place is just across a main road from both the Acropolis Museum and the Temple of Zeus Olympian. Initially the area looks a bit industrial but within 5 minutes you are in the scenic Plaka area near all the major exhibits. We liked the location.
Despite the main road, the apartment is quiet and we slept really well during the stay. It's a really nice place with three bedrooms around a kitchen and living area. There is a separate room upstairs (outside the main apartment) with views of the Acropolis.
A few welcome treats were much appreciated. We would stay again.
