Not heard of that. I’m assuming it’s a bit out of the centre?
No worries.
One piece of advice I would give is make sure you check where everything is. More than any other city, Lisbon is spread out with some of the major sites miles apart.
We found the trams a bit iffy and just bloody slow. Some of the buses were useful and the metro was great for getting up to the Expo 98/Oceanarium zone but it doesn’t cover the Belem area.
Uber is your friend - really cheap and very quick. As you’ll see on the Cristo Rei video, 12 euros from the city centre to the Cristo Rei with the fantastic bonus of going over the magnificent suspension bridge.
Anyway, hope you have a great time.
