I had a very good communication with Berk.
I recommend his house because it is well positioned and the living room and kitchen have a great view, especially at night. The mattresses are very good, you will sleep very well.
What I didn't know is that the apartment is on the 4th floor without an elevator and parking is between € 10 and €15/day. You can't find free parking spaces without paying. From the second bathroom (crowded with cleaning products) you can only use the toilet, there is no sink and the shower is not great. I was also expecting a better cleaning and fewer clothes of the owner in the closets. Overall I can recommend this place for 2 friends couples.
