Large, light space in a good location near Euston Station. We were in a first-floor flat across the street from a lively pub. Although the windows had restrainers that limited their opening, most lacked proper locks, so we couldn't fully close them. As a result, we could hear the revellers at the pub, as well as the underground trains that rumbled along every few minutes. It wasn't loud enough to be disruptive. (Might not be ideal for light sleepers, however.)
There were a couple of maintenance issues with the flat - loose floor tiles in one of the bathrooms, a bathroom door that didn't close, and an intermittently chirping smoke detector - but we appreciated the amenities (washer, dishwasher, WiFi) and enjoyed our stay!
