we stayed at Emrah's for two weeks and it was perfect! the location is great, apartment is only a few metres away from the metro stop that takes you everywhere in Istanbul. the apartment has everything you need, from pottery to towels and everything is just as you see in the pictures.
We didn't get the chance to meet Emrah,but he was always available via text for whatever we needed.
If you're a light sleeper then this might not be the place for you, since there is a bar downstairs that plays music til late hours, for us it wasnt a problem at all tho! would definitely stay here again!
