We stayed at the Hub by Premier Inn Covent Garden for 5 nights and we were very pleased. While the room is quite small, we didn't spend much time in it, and it was efficiently laid out to allow for maximum use of space (e.g., pull-out luggage rack under bed). We did end up "flipping" the pillows to the other end of the bed to allow for both of us to use the shelf as a nightstand, since the mattress was against 2 sides of the room. The hotel was a quick walk from 2 Underground stations as well as a bus stop, with many dining/bar options available within walking distance as well.
Additionally, we were very pleased with the staffs quick response to an issue on our first night - our air conditioner unit was dripping and creating a large puddle on the carpet. We spoke to the staff and they immediately moved us to another room. They were very helpful and accommodating. Would recommend!
