Downtown Lisbon is certainly a must see in the city. Its broad and ortogonal streets, always nice and tidy, and the proximity to the river will give you a feel only a few cities in Europe can match.

Only travelled round her a little but did enjoy it very much, actually played tourist on a sightseeing tour for the first time and was worth it to see all that we had missed

The streets are well planned and dotted with centuries old architectural buildings. A turkish restaurant served great Pizzas

This area seems to never sleep. There is always something going on. Lots of cafes, shops, and scammers. Keep your wallet in the front and watch your handbags. I felt safe but on guard. There are warnings galore about pick pockets and scammers. Not much different than most busy, touristy areas of any city. Beware of the men selling "pot" and other things. They are selling fake goods. That's why the police don't intervene. They may even grab your bag or try to steal. And once you encounter one, they swarm aggressively upon you. Just be assertive, if not aggressive and tell them back off. They usually do. But, generally this is a fun lively spot
