The place is just great, the staff is highly professional speaking perfect English. The apartment is comfortable, stylish and well furnished, perfectly clean and very comfortable. Bedside lamps were missing and should be added for complete comfort. On my request a car a transfer to the airport was immediately planned and flawlessly executed despite the ungodly hour, for a very good extra price.
The area is very central yet quiet and well connected, overlooking an art gallery and beside a culture center.
Only flaw, the kitchen is poorly organized. There is complimentary coffee and tea, plus a bottle of water the first day, but no salt, no pepper, no oil or vinegar and only few and not very useful utensils. Dishes and glasses were barely enough but I strongly suggest to add a simple "Speciell" set of Ikea utensils to make cooking possible. Also, adding some soap for the washing machine would help, though there is a well supplied market at a few meters.
But no place is perfect and these few details would make A Studio Apartment the perfect place for a pleasant stay in Ankara. All in all I have been very happy and I would strongly advise the place to anyone.
