Stay at the Travelodge if you want a cheap room that is usually clean, no frills and basic amenities. I stayed here for 12 pounds per night on a special rate. I needed to be close to London without London prices and got a rail pass, since its main advantage is that it is literally 1 min walk from the London/Stansted/Cambridge line to London Liverpool Street. The receptionist was fine on checking in, but there was usually no-one at the desk. They don't promise much, and you don't get much beyond a bed, a bathroom and a basic TV. There are tea/coffee making facilities, but as other reviewers have pointed out, the room is not that big and the extra sofa bed had definitely seen better days. The security is ok since you need your room key to access the hotel beyond reception, but there was no-one there to monitor whether others were being let in. The only other selling point is that it is smoke free, which may be important for some customers.
