I booked Sertac's place for two days during my visit to Istanbul. I was looking for a calm location with good internet and office space to work, at the same time be closer to all the key spots. This is one of the best locations and met all that I expected. It was a lovely studio with a comfortable bed and sitting area and kitchen. Close to plenty of shops and some good restaurants - and just a few seconds walk to Sertac's cafe serving some great breakfast and hot drinks. Sertac is friendly and made sure my check-in and stay goes well. And he was kind, helpful and always available when I needed some help during my stay. Would be happy to book again when I am around the area next time. Thanks.
