I try not to let my curiosity get better of me when I see a
hidden post.
I guess a rate of £48 is hard to resist and perhaps for that reason, this hotel seems to be weirdly popular on other forums too... I find Romford to be a truly awful place and I say that as a former resident of Croydon.
Once I was driving past a local primary school at the end of the school day and watched kids under 10 lighting cigarettes and vaping as they set off home, including some with their parents(!)
If you do need to be there for work it sounds OK (a photo of the room would have been nice to see exactly how small it is, but never mind) and the building is probably far enough from the ring road to avoid the noise from car owners who need to overcompensate for something...
I agree you can't beat the location if you want a destination served by the Elizabeth line. Bear in mind the direct service to Heathrow is only half-hourly although you can easily get off and wait for the next train once you are in the Crossrail core.
I believe this hotel was only ever used for irregular migrants and never open to the public, until it became a Spark. If Spark is meant to be "premium economy" as described by Hilton, what does that make Hampton?
