Outstanding stay near Galata Tower (if you've never been to Istanbul before, you will appreciate it afterwards).
The apartment is in a very busy area, so if you're very sensitive to evening streets, just bring earplugs.
The host left some sweets and drinks in the fridge which was unexpected and highly appreciated. It showed care.
The shower was a bit of a mystery at first, but after one day in the city, we realised it was a mix of a Turkish hammam with a usual shower head. This was confusing at first, but it became a huge plus afterwards.
I can only say that I will 100% come back. Hugely recommended!
