The place is amazing. The view is breathtaking and very chilling.
The host is super awesome that you wish he could join your trip all the time.
The neighborhood is very simple and quite and once you get down the main area you will find it busy and full of life. I didn't think I would say this but I really loved Uskudar that I kinda missed it sometimes.
Every thing is close by, the metro is about 10 min walk.
The only thing is that you have to climb a little bit on your way to the apartment and to me it was no problem at all I even enjoyed it.
The building is new and very secure.
I highly recommend this place.
