The photo was taken in March, 2018. I was walking around Plaka area last Sunday. Plaka Anafiotika looks like Santorini actually. Houses are white and blue, and the area is so calm if you can ignore many tourists. Anafiotika is one of the places I really like to walk around. You can get relaxed, take some pictures and enjoy the view. It might be a good Sunday activity. This area is 10-15 minutes far from Monastiraki Square, so you do not even need to walk a lot to find yourself in this beautiful district. I would suggest you to get there in the afternoon and walk around for a while before you have a dinner in one of the restaurants around the area. They might be a little bit more expensive than others but it is definitely worth it. :)
