Location: in the Old Town on a quiet street. A few minutes walk from the attractions such as Blue Mosque, Archaeology Museum, Ayasophia and 20 mins or so to the ferries at Eminonu.
Access : Mehmet arranged a transfer from the airport. This made finding the place easy though the address is on Google maps. Keys were left with the driver. Property is narrow and high, as so many are in Istambul. I was in no 5 which meant 4 flights of stairs. You will need to be able to able to do those stairs.
Facilities : a small apartment with 2 ring cooker, fridge, cumfy chair, wardrobe, basic crockery and cutlery. Good aircon/ heater and radiators. All as described. No microwave, no table. Small bathroom with powerful if tempremental shower. Bed hard, which suited me but perhaps not everyone. Two other chairs, one broken. Tv with local channels.
The view: no balcony but door with rail. Looks over a bit of (new?) city wall and a patch of the Bosphorus. Will never forget the hazy sunrise over that patch of water with the oil tankers etc floating by in the distance.
Good to know: the key ring is the power card. Had to ask. This means when out the electricity goes off, including air con of course but also fridge, your phone charger,I think.
Value: basic but inexpensive so I thought excellent value.
Best bit: the location and view.
Less good bit: little really, remember the stairs.
