Overall this is a worthy place, the place is 15min walk to both shishli bus/underground stations (FYI this is the centre of Istanbul European side transportation), inside the place the furnitures are really fitting traditional Turkish lifestyle which is good for the foreigners here to experience Turkish culture. The host is young and friendly, he speaks commutable English and replies almost all day round in 10min.
However, there’s a significant demerit of the place that the internet is unstable (which is a very common old neighbourhood problem that everywhere else of the same type on airbnb will probably have it). During my stay of 18 days, there were 5 internet losses over 3 hours (one over 12 hours caused a really serious problem of my online work), also countless internet loss of few seconds (might cause problems if you decide to play some online games during the stay). If you also have strict internet requirements like me, you might need these informations.
