My wife and I stayed at Tulip Guesthouse for three nights during our visit to Istanbul. The location is absolutely superb! Within walking distance you can visit some of the major attractions of Istanbul. Although the room was rather small, the bed was very comfortable and all was kept meticulously clean with fresh towels every day. We really liked the breakfast on the top floor with a view of the Bosporus. In short: great value for money and wonderful staff!
