Overall, it was a very good experience. Both Adnan and the lady who looked after the place were kind and friendly and did their best to make sure we were comfortable.
It is highly recommended to have a car, otherwise commuting to Istanbul would be challenging.
The two shower systems (in general, bathrooms) could be upgraded. Also, when we walked into the place for the first time, the two washrooms were smelling noticeably. This was an indication of home being vacant for a while; in which case frequent toilet flushing would have been helpful in reducing the smell.
One thing that really stood out and caused discomfort was a strong smell of sewage, especially at night times, coming from the neighborhood. Although, this does not have anything to do with the landlord, it needs to be addressed to the local authorities.
Finally, even though we did not have any problem with this, be mindful that firewood for BBQ and fireplace does not come for free and it should be purchased.
