Mustafa's place is a wonderful gem! It's located in the heart of the old city, right next to the magnificent Blue mosque but still away from the hustle and bustle. It's perfect! We were a family of 8 and the children slept on 5 good beds in one of the bigger rooms. The apartment had great views and lots of space. The apartment itself is delightful because of the small touches Mustafa leaves in his home (as I understand it it was his childhood home) so there are paintings on the wall by him, handcrafted beautiful items on the shelves and even a small pot in the kitchen from a century back. He has even lovingly restored the floor by hand. You can feel it's a place full of love. Mustafa, himself is gracious and friendly and always available to help. He bought us loads of groceries for our stay (!) and we had full access to the washing machine and dryer which was so handy for a full family. We had some lovely conversations with him and we talked about both of our love for families (ask him about his!). He also was very helpful, giving us metrocards, maps, helpful hints and he even let us keep our bags there while we travelled around Turkey. He also has an eye for small details like leaving binoculars for us to watch the dolphins in the morning and making sure he carried the bags up the steep stairs for us. All in all, it's a gem of a place with a gem of a host and it really made out first stay in the country so wonderful. Two things I should say, is that the bathrooms are a little tight and if you have anyone older or with knee problems the stairwell might be a bit difficult but again, for us this didn't matter too much. It was just wonderful and we would highly recommend this place! We would love to visit again and we will be sending our friends this way too. Thank you Mustafa, our family loved it! :)
