Very basic accommodation in a good location. Overall a pretty good value. As is evident from the listing photos, there appear to be several rooms available for rent. The one my friend and I were given was not one that was shown in the listing photos, although it was similar; the main difference was that our room was 1/2 below ground.
Comfortable beds. A small closet with enough hangers to hang the clothes we needed to hang. Laundry machine was available for us to use. Bathroom: Shower was hot and with good pressure and shower gel/ shampoo were provided; sink is really tiny; virtually no ventilation in the bathroom (this is common in Istanbul).
Free breakfast is brought to the room and is pretty basic, like a light take on a traditional Turkish breakfast. Probably best to arrange ahead of time what time you plan to have breakfast, otherwise you may not know if/when to expect it.
Cafes, shops, etc., area all very nearby.
