Uber Boat by Thames Clippers vs Lisbon Metro

Uber boat is a good option, we got it all the way from Putney to Greenwich which is the whole route and as someone who lived in London for 12 years it was a great way to see things from another angle.

Use the Uber Boat for a cheap tour of the Thames.

I did the Uber boat and enjoyed it. Cheap and cheerful!

the trip to Greenwich is well worth it. Take the Uber boat.

You don't need to know Portuguese to use the Lisbon Metro. It's very easy to use and everything is signed in English, plus most Portuguese people speak very good English.

Metro shouldn't be too hard without knowing portugese. All you have to do is pay attention to the station "Alameda" where you'd transfer to the green line and then ride that in the direction of Cais de Sodre which is the last station on the green line so all the signs will have that to point out which platform you need to get to.

From Lisbon airport, the easiest way is the metro. Everything is signposted, the machines are in English, and no one speaks to you. One change, you get off near the river, and you walk to Cais do Sodré. It's flat, straightforward, and stress-free.

I don't speak any Portuguese and had no problem with the Lisbon metro. It's one connection, not too difficult.

You don't need to know Portuguese to ride the metro or trains in Lisbon. It's very easy to get between the airport and that train station. You just have to make one switch. Use google maps for exact directions.
