Don’t miss the museums in Tallinn and the old town. Taxi is cheap if called by phone. Don’t pick one up on the street, more expensive.
I live and work in Tallinn as a remote worker for a few clients; internet is cheap and fast. I've half-Australian / half-Estonian, and have Estonian citizenship so I'm not really familiar with the e-Residency program except to the extent that it's clear the government is investing a lot into it.
Seems to be same amount or more drivers than with Uber in Tallinn.. And well priced too. We were driving in and outside of Tallinn for a couple hours (visiting some suppliers), same driver, waited for us when we made stops. 25 euros on Taxify
