I stayed at marmara during last week of Dec 2017. I enjoyed my stay thoroughly. It is very nice place to value the money and time. Location is very near to heart of Sultan Ahmet square where you find most of the iconic Istanbul sight seeing like Topkapi, Blue mosque, Baslica, bazars etc. The host Elif and staff, I would name Yamur & Hanum and others are very friendly and ever ready and available for help and service. I would highly recommend this place and willing to stay again in my next visit to Istanbul. Last but not least to mention is I faced some problems with lost of my documents in the rush of the city and they helped me in extending my stay at their place and arranged another nice place when their place was full.
