Super recommended!!!
The location is wonderful, just 7 minutes from Monastiraki square. You can reach almost every place by walk.
The bed is very comfortable, the apartment is small but fully equipped and clean. The view from the rooftop is just amazing.
But the best part is the communication and attention from Oltian. He was very kind and supportive and he really helps you if you need anything and make sure that you are comfortable.
And...special mention to his Taxi driver friend who facilitates your arrival and departure at a good price and gives you an interesting conversation via google translator hahahaha.
To sum up, choose this stay, is just perfect to visit Athens:)
