This apartment is great: it’s super clean, spacious, and has everything you need for a short stay in Istanbul. It has some lovely tiled floors and wood ceilings, flooring, etc. It’s on the third floor (no lift) of an old building, on a cobbled street that has the Galata Tower at the end of it. If you’re a light sleeper like me, I’d recommend taking ear plugs. It’s not particularly noisy, but it is an old building, and you can hear the upstairs neighbour walking around on the wooden floors.
Around you there are many cafes, a couple of supermarkets, many boutiques, and a lovely bakery near the Tower. There are a few public transport options nearby: metro stop Sishane, funicular stop Túnel, or a tram which is 10 mins walk downhill near Galata Bridge. You can walk to the square with the Hagia Sophia, etc in around 30 minutes.
