Highly recommend Furkan's place!
For any people visiting Istanbul for the first time, I definitely recommend staying here in the Galata area instead of near Sultanahmet Square, which is way too touristy with people constantly badgering you to eat at their restaurants.
The place is just as pictured. Main bedroom and loft above the projector both have very comfy beds. The projector was great to watch the World Cup and Netflix on. There is everything you need here to have a comfortable stay whether it is a few days or even weeks.
Only issue is the shower temperature which was mentioned in previous reviews. It rapidly changes from cold to hot while you are showering. You definitely won't be having long showers but we knew that when we booked so totally fine with it.
Furkan is very helpful and responsive. We had a bit of an emergency and locked ourselves out at 4am, we called Furkan who thankfully picked up and was able to sort out a locksmith for us!
