Stayed at Mahmud's place for five days in July. I highly recommend it to any one who is looking for a place in Istanbul in Sultan Ahmet Center close to most sites which are a must see. It's modern, very clean and comfortable. We had five family members (adults) so the four bedrooms and four full baths were very much appreciated. The residence is within a five minute walk to Aya Sofia Museum, the Blue Mosque and Topkapi Museum in Sultan Ahmet center. Mahmut, the host, is the best! He was very nice, accommodating and knowledgeable with information for our visit. Always, just a phone call away. Thank you Mahmut !
