Nyugati metro station to Kalvin Ter area

This video was followed by after my breakfast at the McDonald inside the Westend Mall.
However, as I began to (attempt) to head back home, the unexpected thing happened when a portion of the M3 was shut down. I then had to learn how to navigate back to my rental place.
Of course, I could have used the 'bolt' (like that of Uber) app to order a taxi; but that would not sound too exciting at that moment. Hence, I kept trying to find the 'long' way home just so I could see Budapest more from different perspectives.
My other options was to find Bus # 9. At first I saw the sign for the bus. However, once I got to the bus stop, I could not find the route map to head back to district VI (my lodging).
After walking the underground metro tunnel for a while, I found Google Map showed that I could take Tram #4 and then Metro M4 to get back to my street. And that was how I got home on this fun and crazy logistic navigation day.
I learned more about the public transportation today as I was getting used to it.
Love Budapest !!
Cheers!
