What can we say, we had a great stay at Recep's place. The location is great, really a few steps from Taksim square, and everything we wanted was therefore near. Though there is perhaps little privacy, since you do share the appartement with Recep, it is absolutely no problem as he is a very kind and easy-going person. And of course for that price one can only be happy. Mind you, as others had written, that Recep does not speak English so communication goes through (SENSITIVE CONTENTS HIDDEN) translate, though for us that was not a problem whatsoever, at times it was even pleasant for it didn't force us to socialise. Also, Recep makes great Turkish coffee!
In sum, if you are looking for a nice, cheap place that is centrally located, we recommend a stay at Recep's place!
