We had an amazing stay at Haroula's place! The check-in and communication with her and her daughter was very smooth and the place was just like in the pictures. Even though they were not able to meet us upon our arrival, we were welcomed by homemade baklava made by Haroula :D
As mentioned in other reviews, the neighborhood has little to offer, but there is a 24 hour open bakery, and it is three metro stops away from the Syntagma square. Another advantage of the location is that it is 10 minutes away from the main railway station by foot so it is very practical if you are planning on visiting Meteora by train :)
