Nasos was very helpful and responded quickly to questions. He greeted us on arrival and provided helpful tips for the area. He helped arrange transportation too! There's a small grocery store 2 minutes away for necessities as needed and all the sights are within walking distance. The location couldn't be better! 15 min walk to Acropolis, 15-20 min walk to the Plaka, restaurants, flea market and other sites . The apartment is immaculate and comfortable without being luxurious. Clean linen and towels. Nasos provides coffee, tea and a couple of snacks which we were happy to have on day 1 until we found the shops. Grocery store 2 min walk and a lovely neighbourhood restaurant around the corner with prices a little better than in the centre. Coffee shop around the corner too! Apartment is in first floor of the building with only a few stairs in the lobby and the neighbourhood is safe. We highly recommend Nasos apt to anyone travelling to Athens.
