I do recommend Lukasz´s place since he is a very nice host. Check in was super easy, communication in general as well, he is doing a very good job. I believe that he can be and is willing to be helpful in many situations.
Regarding the place, there are a few things that are good to be pointed out (although not necessarily negative). The room doors are not possible to lock. And the other bedroom of the flat is also being used for Airbnb purposes. Also, there lives a cat that is able to open the doors of the room and basically enter whenever. The cat is a nice fellow but can wake you up sometimes. Finally, you really do feel Schottland around, because the isolation of the building is not worth much and the cold weather just comes in. So, pack a warm pj´s!
