Zeynep's place was perfect for our stay in Istanbul. The apartment is as shown in the pictures, with one bedroom and the living room/kitchen combo with a bed-sofa.
Lots of personal touches like the beautiful ceramics from Zeynep make the place very cosy and comfortable.
Zeynep also provided Istanbulkards for us to take the public transport, and local tips for places to go.
The apartment is located very conveniently in an area with lots of little shops and restaurants. Also it is super easy to get to the major tourism spots by taking the T1 metro/tram line which takes you directly to the Blue Mosque or the Grand Bazaar.
We would definitely stay again at Zeynep's place, and recommend it to others.
