We stayed at Deniz's Apartment for a month with our baby. It had everything a family would need in the apartment and in the local area. It is very well equipped by Deniz, and especially clean and cozy, it felt like home after a month! and was spacious enough for our baby to really enjoy the space and crawl around. He was very helpful when we arrived and even waited for us when we were running late, and he always checked up to make sure we were okay and if we needed any help or advise or for any travel questions.
The second best part of Deniz's Apartment - the local area! Honestly an amazing neighborhood with all the different shops you could want 30 seconds away, the bakery, cigkoftesi, supermarkets, barbers, groceries, butchers, household goods, a mosque, cafes and loads of food! - an extremely friendly community. There's also a nice surprise every Monday!
We were only a few mins walk away from the bus stop, metro station, taksi rank, dolmuş and even well known car rental places, all which proved really useful. Fistikaci (the local area) is such a well connected area, you can get to Beşiktas, Sariyer, Eyup, Eminuno, karakoy/Galata, Sirkeci and Yenikapi (for Sultanahment and haciosman line), Ortakoy, Camlica, Umraniye (for shopping!) Kadikoy and much more... all with relative ease and cheaply.
Deniz's apartment is only a 15 minute walk away (or short bus) from the beautiful üsküdar meydan area where you can soak in all the sights smells, and sounds that the bosphorus and istanbul has to offer, from here you can catch a Ferry to pretty much anywhere - this is definitely the best way to get around.
It was the perfect istanbul stay for us, we couldn't have asked for anything else! Teşekkürler Deniz.
