Glenn was a great host. He was very kind and communicative and the place was very clean and as advertised. I was very comfortable through the whole stay and ended up extended it for 2 more nights.
The room was big and well furnished. In addition the location is great, really close to the tram and a quick ride to the center of the city.
Glenn and his girlfriend were warm and welcoming and I'll book his place again next time I go to Berlin.
