I am telling you, it is a great accommodation to enjoy Athens.
We had stayed for 2nights in Athens,
Thelma’s place is good location to travel Athens as it is less than 10mins walk from the station. This station is just a few stops away from Monastraki. She recommended some local places, so you are fine even if you are not ready for travel.
My favourite moment in the apartment was staying in the terrace with having a spinach pie and cappuccino fredo in the morning. Quiet and cozy with your friends and family.
