I'd spent days looking for a place in Athens that should have a view of Acropolis and be close to everywhere. And I happened to find Dimitris's place! (How lucky!) This was exactly what I was looking for and where we should stay. Save your big time without any regret.
The place is very close to Monastiraki Square and main tourist attractions. We were going to take public transportation but since the place is located in the center of Athens, we decided to take some time to walk around to see things around us more closely. (It could've been possible because it was May and the weather was perfect.)
Also Dimitris is so considerate that he stacks the fridge with water (both still and sparking water), orange juice, beer, Greek yogurt etc. Two types of coffee machines are placed in the kitchen depending on your preference and we enjoyed our morning coffee with crispy hard bread and a variety of jam and apples provided by Dimitris. There are more things I'd like to mention but you check for yourself in person. You won't need anything else at this place.
Last but not least, it was marvelous to wake up and fall asleep appreciating ancient Acropolis during the entire stay. We will absolutely come back and stay here again when we visit Athens next time.
