Şerife's place is an old attic flat on top of the hill at the Büyükada island with just wonderful and romantic view. I would not recommend it for people in bad physical condition, old people and such, because it is necessary to walk several flights of stairs to get there and also it is on top of the hill and the only two ways to get there are by foot or by an island taxi, but you have to be agile, get the Istanbulkart (you can't pay by cash, only by the city card) and find the right spot to catch the taxi. It is important to mention (and Şerife should do it in her profile) that the place has a good water filter so you don't have to carry heavy bottles of water, you just have to trust the filter. we drank the filtered water and we are fine, although I also often boiled the water and let it cool before drinking it. Otherwise İstanbul water have a lot of pollutants and sometimes bacteria in it, according to a research I found and almost nobody drinks it without at least filtering it and most people drink just bottled water. The place itself is an old used flat and it's value is authenticity, and some sort of artistic vibe, because Şerife is a painter. We never met in person (which was actually little strange, because we communicated on daily bases, so I felt like she cares about us) there is a box with code lock by the door with a key in it, so she doesn't meet her guests, she just gives them code and let them find out everything for themselves but except of the filter (we didn't know how to turn it on the first says so we had to carry heavy bottles of water) everything in the flat is obvious. When we asked her if there is a delivery service for bottled water she actually made her neighbour's son to bring us two 5L bottles, and that was a nice gesture, I didn't want to give the filtered water to our little son, I wanted him to drink bottled water instead so I would have to carry it all the way and my back is not good and hurts. There is a problem with the fact that Şerife doesn't speak English so you can communicate only through translator in AirBnB app. Which is sometimes weirdly incorrect or the translation is just funny. But in the end it wasn not hard to find understanding and I was always switching off the automatic translation, copied her replies in turkish and just put it in the DeepL. So overall Şerife is a good host and I would recommend her place to everyone, it is beautifully located and very romantic.
