This was an OK stay, and staff were polite and helpful, although the room we were in had issues that we shouldn't have had to find.
The shower was hot & worked well, but did not drain fast enough when the shower was running, so overflowed out of the tray, soaking the bathroom floor. This was partly because the seal between the shower screen and the tray needed redoing, and partly because the drain was not running away fast enough, causing the overflow.
There was a large wet damp patch on the wall (this was a basement room), either from a leak above or in the wall.
The carpet was stained and dirty in some places and could do with a shampoo or replacement.
The non-slip shower mat was rolled up in the corner of the bathroom and was clearly covered in black mould spots and not cleaned, so we didn't touch that, as it was unusable.
The tea and coffee and kettle in the room were fine, and the TV worked OK, but had an All in One remote control, which hadn't been programmed fully, so only did basic operation and couldn't be used to display a TV programme guide, for instance.
WiFi seemed to be quite good.
The bed was reasonably comfortable, but it felt like the mattress was cheap, with some creaky springs in places. Linen and towels were clean and the room overall was fairly clean and very tidy (apart from the shower mat).
Door and building entry was by card, which worked well.
Overall the stay was OK for a cheap'ish stay in London, but maintenance could definitely be better.
