If you are able bodied and fairly fit, don't hesitate to book this apartment. Once you are there it is a very nice base from which to explore this very exciting city. Do be aware that the streets in this area are very steep and cobbled. You then have nearly 100 steps up to the fifth floor. In the apartment there is a step up to the bathroom and the living/bedroom area is split level with another two steps. The view from the balcony is great - endless activity on the Bosphorous. It faces due east, so although you can see Topkapi Palace in old Istanbul, most of the view is across to Uskudur area. The beds and shower are good, but you need to keep the bathroom door shut to contain the unpredictable drain smells. Make sure you arrive with a few provisions for drinks etc, there is nothing there and it is a long way down and back up again if you arrive tired. There is a small supermarket just up the hill, but the street is mainly tourist traders, not local utility shops. Get an Istanbulkart as soon as you can; public transport all over the city is very cheap and great fun, especially the ferries (2 hr trip for about £2.50). Recommend eating in the nearby area of Karakoy. The basilica cistern is a great visit. The best genuine market is in the streets near the spice market. Have fun, it is an incredibly lively city and this place is right in the middle, between old & modern Istanbul.
