If you need to be in Maltepe on the eastern side of Istanbul, then this is a perfect appartment for short stays, and still good for longer term. Its not large but that just means it is easier to live with, in fact perfect if you will be out exploring, working, or whatever most of the your time in Istanbul. Lots of shops nearby on the 'main street' called Ataturk Cd, and the supermarkets are just next door. Also the large Piazza Mall is just 5 mins away. The metro (underground) stop is below the building.
If you need anything during the stay, just ask the owner, and he will get it for you. In my case extra bed linen, towels, etc. It also has secure, undergound parking with direct lift access to the appartment.
It's on the 11th floor so a reasonable view out the window for a city tower block, in fact overlooking the pool, and there are also gym and restaurant facilities at the hotel area.
