We had a great stay here. Nice and clean, very spacious, and our hosts were generous with food in the fridge for breakfast.
When I first saw the photos of the view, I wondered if there was any Photoshopping, but they are the real deal! The Temple of Olympic Zeus is indeed right across the street, and you can also see part of the Acropolis when you are on the balcony.
it is located on a busy street, but soundproofing is great, and you'd never know from the bedrooms which are away from the street. There are a few restaurants and a mini-market around the corner, and lots more choices just minutes away. Google Maps will show you the Acropolis is a 15-20 minute walk, which is true, but that's to the main entrance right near the top. You'll actually find yourself at the museum and the "side entrance", which is the quieter one, within about 5 minutes. The Metro stop is right there as well. The Plaka (lots of shops and food) is just 5-10 minutes away, as is the entrance to the Temple of Olympic Zeus (it's on the other side of the site, so it's not quite as quick to get to as you might think with it being across the street).
Would happily stay here again.
