Really enjoyed my stay at Cennet's place! This is what the original idea behind AirBnb was all about. A friendly host welcoming you into their home. Cennet is just that - always happy to answer questions and assist you during your stay.
The apartment is well-located. It's not close to the city center but you can easily get anywhere with the Metro that is just around the corner. The neighborhood is not as loud and hectic as some other parts in Istanbul are, which is great after a long day of exploring the city. There are quite a few restaurants and other amenities in walking distance and the rest of the district of Beşiktaş has even more to offer.
Highly recommend Cennet's apartment!
