You can travel between two different methods of transport, with one paid fare, within 75 minutes from the 1st journey made. E.g. a bus/underground, bus/bus wouldn't apply.
Other selling points: any underground and some newsagents or tobacco places, they can only charge you 10.20€

Single zone 1 ticket by bus/underground is 2.20€.or buy from TMB's mobile app
Taxi can cost around 30 to 35€ approximately. They should not charge you until you get in, but some do from where they came from if you book by phone, which is not really legal…I never liked taxis...Uber is no longer in operation :(
