The location is absolutely fantastic, in Sultanahmet - 5 minute walk to Topkapi and Aya Sophia. You cannot be more central than that. The neighborhood is quaint, silent and safe at night, with lots of hotels, restaurants, guesthouses and cats. I had a room at the top floor, with a beautiful view of the street and I could even see a bit of the Bosphorus. The room was very spacious, with a single bed with clean sheets and a warm blanket, a wardrobe, and a small desk. You can turn on and off the heating based on your needs, and if you are still cold, the host Mekan will help you to make the room even warmer.
Mekan lives in the room on the first floor. He is very carrying and genuinely interested to meet the needs of his guests. He was open to help me store my luggage prior and after check-in and check-out which I appreciate it a lot as I could freely move and explore beautiful Istanbul. Don't be shy and ask him everything as he will do all his best to help you. You have access to a small kitchen and a bathroom with shower. There are three cats on the property, all of them very cute and well behaved.
I totally recommend this place and I hope to be back one day!
