Was kind of difficult to find because it's tucked away behind another building, but also kind of connected. The building is extremely warm ( especially so during this heatwave) there is very little ventilation, so the heat was a bit suffocating inside. it's very near to the tube, about a 5-10 min walk away, which is convenient.
Also the guest registration process occurs outside of Airbnb, the property is managed by a management company who have their own guest registration process which requires each guest to send copies of their ID, etc, which wasn't super convenient given that airbnb platform is supposed to do that for you.
the host was very responsive, and there is a 24hr reception, so don't worry about being later than expected for checkin.
