Great place for its money, and convenient location. Easy tram access to the historical downtown area, and a 10 min walk (uphill) to the Istiklal, the main pedestrian street of Istanbul. Host is friendly and easily accommodating (much appreciated) for late check-out.
The primary downsides are that the bottom floor room, while looks great on paper, doesn't actually have proper windows, its de-facto on a basement equivalent floor with the building being on a steep hill. Minor things such as lamps being present for visual looks, but no actual socket to plug things into.
Would recommend overall.
