Carolina is an excellent host, flawless communication and she takes great care of the house and guests.
The location is also outstanding. It's only a few minutes from Taksim square and you can get a little taste of Istanbul's nightlife. You can jump into the Metro and see most tourist spots in the city.
Big plus: you can watch over the beautiful Bosphorus at her balcony.
Highly recommended and special thanks to Carolina for hosting me during my introduction to Istanbul. Let's grab another drink some time.
