Gregor wasn't in the country during my stay, so I didn't really interact with him--and yet his team of friends and family that help him run this flat were absolutely incredible. Friendly, courteous, prompt, and so easy to communicate with, they checked on me just enough for me to know they had my back if any problem popped up, but not so much that I felt like I couldn't just make myself at home.
Speaking of problems--there were none. I stayed here for a month as I searched for a permanent place to live. It worked great, the location is great, and the hosts gave me solid recommendations for anything I was looking for. Fast, stable wifi made remote working from my laptop easy. Hot water is hot. Appliances work. Everything is as it is described.
I definitely would recommend staying here.
