Other than what has been said about the 4th floor and no elevator (which is what I expected and didn't mind) I have nothing but good things to say about Kerem's place. He and his brother are top notch hosts. The no elevator thing was already going to be a non-issue for me since I knew what to expect, but Kerem's brother added to my pleasure by carrying the largest of my suitcases up the stairs without my requesting it. I'll be back, and I will stay there again!
Also, it was super clean, stocked with toiletries, and conviently located five minutes wall from the Havabus stop and that or less the square!
