We loved our stay at this apartment! We were a group of 5 friends (a couple and 3 singles). The apartment was so spacious, I didn't feel claustrophobic anywhere. The pictures do a good job showing the space in the living room and the bedrooms.
Bulent is a great host too! He was very responsive before we arrived - arranging our transport from the airport to the apartment with no hassle. He also met us at the apartment and gave us a tour.
We mostly used taxi getting around the city from the apartment. There are a couple hotels around the neighborhood with regular taxi lines. I think there are a lot of public transportation available, but we opted not to use it.
I recommend groups to stay here and I would love to stay here again!
