Sabastian's place is in a great location in London, close to great pubs and interesting spots in the city.
The place is basic, not somewhere you want to spend time in. Water pressure was a big issue, effectively there is no shower - I had to go elsewhere to shower everyday which was far from ideal. The bathroom also had a lot of black mould on the ceiling. I took a video of the bathroom / shower set up at is it was comically bad.
I also had that "waiting for check-in" experience where I was in meetings (calls) waiting on the street with my bags.
The experience put me off Airbnb (I am a long time bnb'r), I got a hotels for the rest of my trip.
