It was very basic, there is no point saying otherwise. It was a small, basically furnished room with a shower room attached.
However, it was clean, everything worked and the fella in charge couldn’t do enough for the guests.
The single biggest plus was the location, it was outstanding. The were plenty of shops and places to eat right on the doorstep. Crucially, both tourists and locals ate in the restaurants. The food was very good value and of a consistent high standard. The locals were incredibly friendly and the whole place seemed very safe. The main tourist sights around the Ayasofia were about 10 minutes stroll. If you’re on a budget, you couldn’t do better.
