Amazing Apartment! Its near to all the main attraction and still away from overcrowded chaos, apartment has everything you need, terrace was beautiful, check in and check our were extremely smooth, Toni was very extremely courteous and messaged us regularly during our stay to check if we are okay and like the apartment.
You can get a bus to Syntagma just by walking 100 Mts and if you are a group of 4-5 people you don't even need a bus, you can just grab a taxi which is like 3-5 euros per trip.
We loved the apartment and the host! Highly recommended!
