Nursena and Onur are amazing hosts.
Let me start with the unfortunate problem. 2 days before my arrival, Nursena informed me about a big storm in Istanbul that damaged the roof and some water entered and damaged the ceiling as well. She offered me the possibility to cancel, even after sending people to fix the roof, since it wouldn't have time to repaint the walls and ceiling.
I decided to stay and it was the right choice. The apartment is simple, but big and very functional. Some furniture is still a bit old, but doesn't bother the experience at all.
I've been in contact with the hosts during the whole stay, daily, because when we arrived some water started to drop again from the ceiling, but this time because of the neighbor building, they tried to fix and contacted the neighbor immediately. At the end of our week stay the problem seemed solved.
The cleaning of the place is very good, even sending extra air fresheners to help with the smell that the ceiling problem could present.
The location is very good, near hotels and taksim Square, although a bit tricky by car during very raining days at night, as it was my case. But I believe that this was due to the uncommon storm of the days before, since the area was quite nice.
For working travelers, like myself, the internet works well and it was stable during the whole week.
I highly recommend the place with the problems solved, and I know that if something unforseen happens, the hosts are ones of the most prepared and interested in solving that I've seen.
