The studio is in a great location, small, but fine for 1 or 2 people.
The only negative is the bathroom smell.....I'm sure unavoidable though as it's an old building.
The wifi & heating are excellent.
We arranged a pickup from the airport with Pelin's partner...a bit more expensive than a taxi, but after constantly travelling for a year......justifiable & easier.. We organised a lift back with him to the airport for the taxi price too.
Pelin also washed our clothes for us at no cost, so that was really welcome & helpful.
Pelin was easy to contact via texting & responded quickly.
If I need somewhere to stay in Istanbul again, I would definitely return.
