We have used Britannia several times in the past, and quite enjoyed it, but always thought that it was a bit tired and needed a little bit of an update. While that is still true, they look to have started some upgrades as we noted fresh paintwork in rooms and new carpeting in corridors - a good start. It was good value booking through “Trip”, and well worth the money we paid. The bar area is nice and open, though like most hotels, too expensive really. You also have choice of a pizzaria and conventional restaurant.
The only thing we didn’t like was cost of parking… as we think £25 for 3pm till 5am was a bit rich.
Overall, though, a pleasant and comfortable overnight stay, with easy 15 minute early morning car journey to London City Airport.
