Day 4 in Europe--Strolling through the streets of Lisbon

Everyone says you should take a ride on Tram 28 in Lisbon, but when I see the tram packed with people, I lose interest. I've walked through these sights over the past few days. From the Upper Town to the Central Park, and then to the Liberty Avenue, today is Friday, and on one side of the pedestrian walkway of Liberty Avenue, there are stalls set up along the road, stretching for a kilometer, right across from the upscale boutiques along Liberty Avenue, which feels quite harmonious. I didn't take the tram, but walked along the 🚃 tram route, up to the viewing platform, and once again overlooked the old city of Lisbon from another angle. Lisbon has a pleasant climate and nice scenery. It's not luxurious but feels especially comfortable, suitable for a short stay.
