You really cant go wrong booking and staying here, Yusef made us feel like a long time friends and helped with getting the best out of the time we had in Istanbul.
Very sociable host and helped with restaurants, direction, tours , best places and 'why'. There is a number of apartments that they have in the building and when I needed an extra night, he went out of his way to make sure it happened.
There were a couple of small issues with things not working when we checked in, but these were attended to straight away.
I would stay here again, no doubt!, it is close to all the main attractions that a first time visitor would wish to see, and all within an easy walk.
Highly recommend you try!
