We stayed in the hotel Plaka in 2019. Lovely hotel. One entire floor given over to the breakfast room, that also served complimentary drinks and biscuits throughout the day if you needed a sit down and recharge in your sight seeing. Beautiful view of the acropolis, lit up at night, especially from the rooftop bar.
I was in awe of the lady who went round each morning talking to each table and making recommendations for their day depending on their plans. Speaking in several different languages depending on the guests.
Nice little square in the centre of Plaka itself.
Turning one direction was lovely, in the direction of the ancient sites. Walkable. Felt safe.
Turning the other direction I was less keen - lots of begging (with children on laps whose job was to sit there all day), and approaching you to sell things in the street. I was less of a fan of that. Lots of graffiti.
We went very off season, which was amazing. They'd had snow in February in the hills (q rare apparently) and despite that it was q warm but we could walk and walk without getting hot and bothered.
