We loved this place!! It felt like home! Romanos and Nikos were amazing hosts, always super helpful and accommodating! The balcony is definitely the highlight of this flat, we're missing it already having breakfast here every morning with fresh squeezed orange juice (there's a mixer/squeezer provided!).
The flat is good located, everything is in a good walking distance. It took us about 10 mins to Omonia Square (here's a metro station which takes you to e.g. Monastiraki Sq or Akropolis), 15 mins to the Central Market and about 25 mins to Monastiraki Sq.
We really really enjoyed our stay and would love to come back again! 200% recommend this place and the hosts!
