We spend our first few days walking around and getting a feel for the city. Now, William will tell you that all of our destinations were uphill both ways, and there is some truth to that. Aside from a few east-west roads close to the lake all roads seem to have hills so even if we are generally headed downhill there will be a small upward climb.
We revisit San Martín Square both during the day and in the evening. By day people are lounging enjoying the sun and the view of the lake or taking selfies in front of the Alpine-style civic buildings. In the evening there are street musicians and people sit around listening and enjoying their maté or perhaps a cerveza they purchased at a nearby kiosko (convenience store).
