Exiting the castle, we walked down to the city center, via small alleyways in Alfama.
Not knowing how far we would need to walk before we reached the bottom of the hill, we hopped aboard the #28 tram. A more than friendly gentleman, assuming I understood his language perfectly, decided to be our guide, and instructed us (as I surmised) to carry on journeying in the tram onwards to the Chiado district. On an adventurous whim, we decided to follow his directions and our instinct, and soon we were headed past familiar sights into the unknown.
