Me and my boyfriend stayed at Oznur's place to spend our summer vacation. The room was as described, big, sunny, comfortable and with air conditioning. We arrived at Barcelona with our car and luckly the apartment has its own private parking lot (but we had some problems finding it because unfortunately when we arrived Oznur was in her home country and couldn't show us where it was).
The apartment it's really near to a metro station but it's not in a very central position. We met Oznur roommates, all very nice people.
We are really satisfied with our experience! :)
