The highlight of this apartment is the rooftop view over the Bosphorus strait. We stayed for 7 nights and loved coming back here every night, the rooftop gave space, peace and perspective on this full-on busy exciting city.
The location is the best. Near Topane tram and a short walk to Galata. There are nearby cafes and restaurants. And you can walk or tram into Sultanamet (which I am so glad we did not stay in) and leave again, to stroll and eat in this district, that's more relaxed and curious to wander the streets.
Communication with host is excellent and they organised our taxis which was so helpful (airport IST public transport is complicated).
The apartment is intimate and perfect for a couple as it is small, and bath/shower is in the bed/living area. We didn't use the kitchen at all. The local restaurants were too interesting!
I will definitely send other friends to this apartment block as they have other apartments too.
