I've stayed at a Roam before in London. On the upside, it was pleasant, clean, quiet, and conveniently located. The room was a bit small and the in-room fridge was tiny, but those are common traits for temporary housing in London.
The real downside to me is a conflict inherent in Roam's branding and strategic positioning. They position themselves as being for digital nomads (i.e. people who are working as permanent travelers) and assume that what I want as such a person is to actively engage and spend time with other people doing the same. To that end they're aggressively friendly, which I found a bit off-putting. I travel to be integrated into the communities in which I am traveling, not to hang out with other travelers.
