Very central guesthouse. Cafes, shops and everything you could wish for is super close.
It is located on a tiny street so it's useful to have the GPS turned on, as even the taxi drivers can get confused :-)
We spent six nights in Istanbul so for us the room was a bit cramped, I suppose that for shorter trips it is OK.
Breakfast buffet type has many options and it's served on the terrace which has a view towards the sea. We loved the Russian cook lady:-)
