The apartment was very conveniently located for exploring the old city. All major tourist attractions (e.g. Blue Mosque, Hagia Sophia, Topkapi Palace, Basilica Cistern, Grand Bazaar, etc) are within a 15-20 minute walk at a moderate pace (possibly a bit longer for some travellers as although the walk is fairly short 0.8-1.5 km the area is quite steeply hilly).

There are also lots of amenities in the immediate vicinity of the apartment (e.g. grocery stores, bakery, precinct full of restaurants).
Something to note about the apartment is that the lounge area is contained within one of the bedrooms, there is no separate lounge / dining area.

Barbaros was a very accommodating host and was very helpful in providing directions to find the apartment when we arrived and arranging an airport transfer when we were leaving. Ali the on-site host is fantastic and will make sure you have everything you need during your stay.
