This place is really spacious and really clean! The host is also very quick to reply our queries. Walking distance to a lot of the tourist attraction in Istanbul like The Blue Mosque, Hagia Sophia, The Grand Bazaar and the Topkapi Palace. There are lots of cafe and restaurant near the area. The only issue would be that there are lots of uphills to climb, but hey, it's Istanbul so you will have to expect a lot of uphills!
We had a good time in this apartment. My family and I had a unique experience taking the lift everyday as it is very different from the ones we had in our country. Totally recommend big groups to stay in this place! You'll enjoy it :))
