Efe & Memet's place is awesome. Actually the previous reviews reflect this. I would only add that the views are really amazing. Me and my husband liked it a lot. Also the place is well located. From the Taksim square you can take Havabus to Sabiha airport or take the public transport to navigate the city.
Special thanks to Memet for his hospitality and fast responses.
Highly recommend this place :)
