Such a unique place to stay in a great location! Rana and Rob are very accommodating hosts they are both artists and you can find some interesting art pieces at display. The place in general feels artsy, cosy and authentic, you can even buy local artworks/clothings here.
Besides that, in 1 minute walk from this place you have all the antique shops and galleries, 10 minutes walking you are in Istiklal and in 5 minutes you have the tram station to access all the historical sites. Unlike many places in Istanbul, you don't have to climb stairs or hills to reach this place.
I would definitely come back and suggest this place to anyone looking for a stay in the heart of Istanbul.
