We were a group of 4 people - a couple and two friends, so we all had our own bedroom. The location was great, around the flat there were a lot of pubs and shops and public transportation was right around the corner. It's location is in Shoreditch, which seemed like a hipster area with many cool and modern restaurants. (If travelling as family with kids, I would not really recommend this area - many pubs, people and alcohol)
The pictures are quite old, so the condition of the flat is not as good as shown (especially the bathroom - shower ceiling had a crack and was kind of black). But the cleanness of the flat was absolutely stunning.
Sam was always reachable through airbnb if we had any trouble and check-in went smooth.
In a nutshell, it was a wonderful 4-day-stay in London and the price-performance-ratio was reasonable. Only negative point was the bathroom condition, the rest was absolutely great.
