I stayed at Dundars in the middle of my trip and then booked again for the end of my trip as it was so convenient. It is a lovely apartment with a very artsy and funky vibe. Dundar and his girlfriend are lovely and full of very useful information including where to eat, shop, drink and visit. I think I stayed in almost all of the rooms available and they were all very clean and comfortable. The apartment is quiet and well lit and includes a very cute and friendly dog who is surprisingly quiet. I will certainly stay here again when I return to Istanbul. Oh and you should definitely try Dundar's turkish coffee in the morning. Perfect to get you through the day!
