Alex is a really nice, chill and fun guy!
We haven't been the easiest guests to have but he was always understanding, kind and helped us out where he could.
The location is not the closest to central London (takes round about 40 minutes to central London) but easy to reach by public transports (next bus station 2 minutes per foot).
The room wasn't the biggest but could fit for four of us. We stayed there for four nights and had a really good time there!
