We stayed at Demir's place for about a week and everything about our stay was perfect. The apartment came with a ton of amenities and we had anything we could possibly need. Very cosy, spacious and clean apartment with great views of the sea. Close to banks, shops, subway and ferry stations. Our check in was managed by Guli and handled perfectly. The apartment made our trip to Istanbul so much more memorable and comfortable than it would've been elsewhere. Highly recommended.
