We stayed 4 people(2 couples) in the apartment for 4 nights.
The host was helpful with everything and very friendly. The apartment is nicely decorated and clean.

The apartment is located in the lower sultan ahmet area in the bottom of a shoemaker street. The street itself is remarkable, they produce soles, shoes and accessories for shoes- by hand(worth seeing). Its got a local feel in contradiction to the upper sultan ahmet area near aya Sofia and Sultan Ahmet mosque.
Close by youll find local eateries and some touristy places. A fruit dealer is you closest neighbour in addition to a traditional mens cafe. There is a hairdresser close by, several bakeries(30 sek walk), a grocery store(30 sek walk from the door) a yufkaci(place where they bake yufka).

If you walk straight up the shoemaker street for about 10 minutes you reach the grand bazaar(kappale carsi) and the metero/tram.
I found the area quiet at night and was not bothered by anything while sleeping. I have previously lived in the sultan ahmet upper area and i prefer this location because of its local feel and the opportunity to avoid all the touristy places(which are really expencive in comparassment).

Highly recommend this apartment, but due to stairs and no elevator, not suitable for disabled. I might add, we all felt safe the entire stay.
