My stay at this place was very nice. The apartment itself is indeed spacious, it is big enough for 6 people to live in it. It is surprisingly quiet and private given it is located in Beşiktaş, a nice and busy place filled with different restaurants, bars and a lot of people.
Towels, shampoo, hair dryer, iron and various other amenities were provided. The kitchen has an oven and a stove and a small fridge, it was sufficient for making simple meals.
The host himself was very helpful, attentive, friendly and understanding. He was ready to help anytime and was quick to respond. He checked on me via WhatsApp a few times during my stay to make sure everything is going well. He was understanding and flexible. I broke some things during my stay but he didn't react negatively. He even offered me the rest of the money back after I offered to pay for the damage I caused. He is a very nice guy and the visit was made more pleasant due to this.
I would recommend this place if you travel in a group and or enjoy your privacy at a good price.
