I stayed at Martin's flat from 29/2/2016 to 7/3/2016.
The pictures are accurate, the WIFI is fast and reliable, and the host, Martin is friendly and promptly replied to my emails.
However, the bathroom was a disappointment.
The shower's hot water pressure is very low when it flows at all. Hence once you turn on the cold water just a bit to get warm water flowing, you end up taking a cold icy shower. Result: During the length of my stay, I showered under icy cold water.
The flat will be fully functional when this issue (major in my view) is fixed, which seems to be in the hosts improvement plans.
