Great location next to metro and within walking distance to all main attractions. very clean and spacious. Be prepared to carry your luggage up several flights of stairs. For a simple delcicious meal or takaway try Istanbul Kebab 10 min walk up the street at populo square next to train terminal /Burger King with freshly made generous portions of kebab at 4Euro. No large supermarkets nearby. There is small carrefour at vittoria the next street, coop down road, and a slightly larger one on way to trevi fountain
