To start with the location; if you are going to spend most of your time in Syntagma square shopping the apartment is far from you (because you have to go back and forth to put your bags and each time you have to walk around 17 min to arrive to the apartment and 17 min back to Syntagma) other than this the location is just perfect, a spectacular view to the Acropolis from your balcony.
The apartment was just right for us, but you have to know that if you have more than 2 big bags you will find it small.
And finally, let us talk about the amazing hosts!! They are so nice and kind, always there for you and ready to help at any time and when you message them the reply will be ready within seconds :) so happy to meet such nice people.
