Look for 9 - Limani.
There's a black square mark just above it. Go past that and walk towards 8 - Eleonas, and it's about 100 metres up that road - on your left. Look for the Secret Nest Taverna (good fish there!), and Dora is part of that group of buildings.
It's visible from 11 - Costas & C and just a couple of minutes walk. If you're with Olympic, you'll have use of the pool at Costas.
Give my love to Dora - she's a lovely lady!
