We stayed at Guiseppes place for 4 days. And it was wonderful. The apartment has sunlight in the mornig and in the evening at the terrace. The apartment is located very central in cihangir which is great to discover istanbul... nice cafes and bars and a supermarket nearby.
guiseppe has a very helpfull assistent we communicated with and check in and check out worked very easily.
Will come back for sure.
