This is a great find that has all the amenities. It's quiet and located in a good spot in central Athens. I give it a 5 star in all areas except the value which can be very different depending on what time of the year it is. I booked it for a month because I was renovating my own apartment but it was in the middle of a heavy winter and the central heating was not operated. As a result I was strapped with the cost of electrical bills if I wanted to be warm. Other than that I full recommend this place because it simply has EVERYTHING. Coffee machines, all small kitchen appliances, full stove, it even had an electric blanket (wish I knew that on my first day that I froze). Krystyna is very communicative and willing to accommodate for everything that is needed.
I'm happy with my stay and I would book again if needed.
