The Metro is very confusing, especially with all the lines that connect with each other with tunnels and hallways that are as long as walking the above streets themselves. It gets hotter underground than above. It’s easy to miss a turn and accidentally get on another line. I am really bad with directions and my best friend who is good with them got lost here and there. It does make it easier and accessible on a dime to get to some tourist and cool central stuff in the city. A lot of these are within 30 — 40 minute walking distance, however, there were some moments in which we just needed a rest. Price is less than 2 euros each way. This stop was really close to our hotel which was helpful.
