Maria, our tour guide, was so enthusiastic and knowledgeable. The electric bikes were invaluable with all of the hills in Lisbon. We would never have seen what we saw if we hadn't been on this bike tour. Also, another bonus was that there was just my husband and me on the tour, so we had a private tour. I appreciated the bike company not cancelling the tour because of only two people signing up for it. I would highly highly recommend!
