The coolest thing about this hotel is that you can take the pod straight from the terminal 5 to reach it. It does cost a lot (7 pound) but it's still cheaper than a taxi, and the ride is exciting.
The hotel looks old, both from the outside and the inside, that doesn't mean is not well maintained. The design is not very modern, but the room was clean and comfortable, with the nice extra touch of the tea and kettle which I love. Large and comfortable bed, and a nice medium size Samsung TV.
All in all, a very comfortable stay for one night of layover.
