Am here right now for 14days. I'm not one to do some massive trip report, but happy to answer any questions.
With the 5-day test & release quarantine, I selected for a hotel against 3 criteria, which made the list quite short:
* In the City, but in an interesting neighbourhood with some vibrancy/energy (think more Brooklyn/Queens than Manhattan FD)
** Shoreditch is a bit more like Brooklyn 10-15yrs ago, not Brooklyn today, btw. A tad gritty, but not bad. Might not be where I put my Mom.
* has a well-regarded resto, as am stuck in here for 5days eating their food.
** man, a good choice in this aspect. The F&B here has been GREAT, and the bar/resto staff are all friendly & helpful
* has a proper fitness center (a rarity in the City)
** nothing special as far as hotel fitness goes, but for being in the City and at the price, is great. Enough to get some workouts in.

Whoa, who knew, these guys are in their soft opening; they only hired staff in mid-May. So experience may change as they get established.

So far (day8), nothing but good: great attention, great service, solid location. Got a call out for being Titanium (LTTE), and a nice push up to the 'sky floor' as referenced above. Room is a bit snug, but only by American standards. Design of the place is great, very interesting, a bit 'W' but not dark & nightclubby feeling. Lots of natural light, lots.
Cost was absurdly low, but, from discussions here, seems hotels in the City are running 20-50% occupancy, so they are starving for business. Note, after over a week here, have gotten to know these folks. They're at <30% occupancy, as are most hotels locally. Fitness center is okay plus a full sized pool, jacuzzi, and sauna look to be a treat.

They set up a screen downstairs for the England v Italy match Sunday, and the bar is quite a nice place; I would come here for drinks even if not staying here. I like the vibe, the design, the remodel. The staff is solid, and the bar & resto are top notch. I will absolutely look to this place again for next LHR trip, and recommend it.
