The location is good for both walking and being able to jump on/off the Underground.
We did have issues accessing the property (which I understand has since been resolved) but we were disappointed how this was dealt with at the time (cold and dark, locked out of our accommodation in an alley, is not how we'd choose to start our stay!)
We found both our room and communal areas very clean which is commendable noting the amount of people using the bathrooms.
