The place is a small apart-hotel located really close to Grand Bazaar and Blue Mosque. It is about 50 min by metro and tram from Ataturk airport.
Some restaraunts and a couple of grecery stores are right across the street. A few minutes up-hill and you are right on the Divan Yolu street with tram station, which you can use to reach either airport or Galata bridge. Turn left and reach Grand Bazaar, or go right for soem restaraunts and Blue Mosque.
The room have everything you need - double bed, couple of armchairs, a bath, a small kitchen with all pans and dishes. There is a small fridge and cooker. I was able to boil some eggs for breakfast and make a cup of tea. A lot of electric plugs to charge your devices and a TV set to watch some Turkish TV, if you like one :)
The guys are really welcoming. There is always a free tea and coffe in the lobby. The taxi they called my for my trip back to the airport was a nice one.
