I have an unusual question, about Istanbul topography, esp. Sultanahmet area. My dear friend have some limitations in walking distances and hills/stairs. Thus, am looking for a stay in Sultanahmet area with elevator or ground floor rooms. Am having difficulty finding a hotel/guesthouse/apartment from witch to walk to major sites down a slope, not up. Looked at topographic maps, learned that major hill in Sultanahmet is where the Topkapi palace is, and that streets slop down to the Marmara seashore from the tram line, Divan Yoly. Cd. Am I right? Also, am afraid to book a stay somewhere where taxi isn't going to. Marmara guesthouse looks very nice, but is it located downhill from major sites?
Another question. We are staying in Sultanahmet for 2 days, leaving, then returning back for 3.5 days. Where to stay the second time? Love Galata, Beyoglu, but isn't it a bit hilly?
Any advice from seasoned travelers who knows IST well would be highly appreciated.
