I used this forum to help me prepare for my recent visit and wanted to report back and maybe help out a few travelers too.
Lisbon airport: Bolt pick up is now on the same level as the taxi stand. Everything I read beforehand indicated otherwise, but I guess things change fast in Lisbon. When you exit the airport toward the taxi stand, the Bolt pick up area is all the way to the left in a garage area. There will be a crowd waiting around. I've had many drivers cancel due to the bad traffic getting into that area. Finally one driver texted me to meet him next to the taxi line. So we hoofed it over (it helped to pack light). He got yelled at by a guard but hey, he was problem solving.
Most atms at the airport are euronet. I did find a multibanco one near gate 17, looking very inconspicuous near a much larger euronet one.
Strikes: I did not see many mentions of strikes here, but we encountered several: ticket sellers at Sao Jorge castle, funiculars, trains. For Sao Jorge castle, we had bought tix online, so no problem there. Funiculars strike messed our plans for one day, but we were able to ride them on our last day. We took Bolt to and from Sintra (about 50 euros round trip; saved us some steps). But had to cancel our plan to visit Cascais (still salty about that). I had put 10 euros on each of our navegante cards, but struggled to use them due to the various strikes, so ended up giving them to someone else. Bottom line: be flexible and have backup plans, and don't put too much money on your card! Or just use Bolt.
Trams: I had RS 2024 Lisbon guidebook but the info about where to catch tram #12 is already out of date (things change fast in Lisbon). Tram #12 now starts at Martim Moniz, just like #28. So there is one long line for either tram, and #12 comes comes much less frequently than #28. We waited an hour to get on #28 and it was like an amusement park ride, clanking and jerking. Worth it to try once.
Bica funicular: if you want to ride it up hill, the station is on Rua de S. Paulo, very close to the Timeout Market. Coming from TM, I was using google map to find it but google did us dirty and directed us to walk up the steps toward the top (which, those of you who've seen it, know how steep the climb is). We wised up part of the way and retreated our steps downhill. To be fair, this is the only time google map failed us on this trip.
