Istanbul is a city of hills. Streets can be steep, very steep, or enormously steep. To walk is to work out. To drive is to crawl. In Beyoglu, the commercial center, there are several incline trams in tunnels to take you up or down. We stayed in Beyoglu at the Aloft Hotel, and were rewarded with a stunning view - a panorama of giant mosques across the Golden Horn of mythical fame (see above). We were also just downhill from the Galata Tower, our beacon to know where we were as we navigated the short, narrow, windy and usually unnamed streets. The streets are so narrow there is no room for sidewalks, and where there are sidewalks, there are foot high concrete markers to prevent parking on them. Some intersections are so tight it takes ordinary cars two tries to make the turn. As usual in cities, we walked all day long. Everyone smiled and was eager to help. It was a great trip to a world-class city.
