I'll try to sort out a few more pics, but as my daughter says, you're better going online because you'll probably get a better photo! Anyway - favourite parts. Well, how I work it is... look at Tripadvisor, Lonely planet etc. for the 'must see' attractions, and then avoid them like the plague. What we really enjoyed in Lisbon and other cities, is to get off the beaten track and explore the maze of tiny streets of the old city. There are free walking tours that will take you to these, but we prefer to just go on our own. No map, no satnav - just go. It is fantastic the number of tiny shops, restaurants etc.. you find where you can get a decent meal for a few Euros.
Places to eat - again avoid the tourist traps. IMO, the best places are just off the beaten track, down roads that you mightn't normally walk, but are quite safe. If you know Lisbon, then you will recognise the Marques de Pombal area, and that is where we tend to stay. There are numerous small restaurants round there. We've eaten great local dinners with wine for under 30 Euro (for two).
We're not beach people. We have great beaches here, so they're not an important part of holidays. However, most locals go to Cascais which is a beautiful seaside town, about 45 min my train. Public transport is dirt cheap and the return journey is under 4 Euro for seniors.
The Traffic is horrendous, but it does stop for red lights ans pedestrian crossings. The popular way to get about is to hire an electric scooter. I'm busy today, but I'll try to find some pics. (I never photograph food )
