PROs: Location (safe, convenient to airport & underground, pubs in the area), Price (not cheap, but great for London), Staff (available & friendly), Breakfast (quite a few options and friendly staff to make more), Cleanliness (daily room service!), free welcome beer at the pub across the street (great place), checkout wasn't until noon and they were so kind to hold our luggage until evening
CONs: Room & Bathroom were small (but it's London and on a budget it is expected to be cozy), bathroom fan didn't work (but then it usually doesn't at hotels on a budget)
