This is a wonderfull place to rest, you'll live between the business and turist parts of the city. If you'll go to Taksim, you colud see the main square for walking. If you'll go to the left from Taksim, you can see quarter with expensive hotels, there is beautiful streets and shops. Of course products in this shops more expensive when other shops in the city. If you will go to the left from this qurater, you could see business part of the city, where you can find exchange with good offer and testy food and others services.
About landlord: Mustafa is very gentle and sensitive, communication with him is beyond praise. His apartment looked like on the photo. If you like smoking, here you could find balcony overlooking the courtyard. Badroom is small, but very cosy and most importantly there is silence and warm. The living room is very big and light. I can recomend this appartment)
