We stayed at Yusuf's for 3 nights for a first visit to Istanbul. The accommodation is spacious and was ideal for this purpose. We were with 2 people and we could easily put all our stuff out of the suitcase. It's located within a 10 minute walk from Haghia Sofia, Blue Mosque, Grand Bazaar, Spice Market. Also tram T1 is nearby. The room is clean and comfortable and is tidied every day. There's nothing to fault. I would stay here again!
