The hotel needs renovation, of course, but it was generally clean and cozy. We were in February, just when snow fell in Istanbul and it was cold, but the room has central heating - it was warm. The views on the roof are simply amazing. There is also a roof floor, it is also warm there in winter and there are sofas and a bathroom, the owner-administrator allowed us to stay there at least until nightfall, this is after the time spent in the room has ended. The breakfasts are without frills, but you definitely won't stay hungry. We liked everything.
Excellent location: 5 minutes to Sultanahmet Square. The same distance to the tram stop. Hospitable host, courteous staff. A normal breakfast, tea, coffee around the clock on the upper terrace with sofas. Quiet street, inexpensive cafes nearby.
