Daniel's place is an absolute treat. I spent 4 days there on a first-time visit to Istanbul. It's a great location for exploring the city - the area felt safe and there was lots to do, and was easy to walk or get transport to all the main attractions. It was spotlessly clean, and is really comfortable and homely - it really felt like a home away from home. One word of warning - the stairs up to the apartment are quite intense if you are carrying luggage (but that was well communicated by Daniel), and the flip side of that is the reward of the breathtaking view of the city from the cute balconies (perfect for leisurely breakfasts)! Can't wait to stay here on my return visit.
