I'll start with the positives. Location, location, location - this is the greatest asset the apartment has going, it's surrounded by nightlife, restaurants, bars, transportation etc. This is the primary reason to book this place, if you're considering it. Communication was easy as well - I needed to reach out just after check in (more on this in a moment) and communication was quick and easy (though not responsive). The shower has great pressure. One note, the host is not Ruth. Ruth may be the owner of the apartment (who knows), but it's clear that a management company is who you'll interface with, should you need anything. This is neither positive nor negative, but it is worth noting.
Unfortunately, the apartment is severely misrepresented in the photos. It's beat. It's dirty. It was barely vacuumed upon check in. The sheets and towels were stained, there was long hair everywhere in the beds. The throw pillows and couch were, frankly, gross. I put the pillows up and never touched them, but felt the need to put a sheet on the couch it was so nasty. Even the curtains had stains and a few holes. There was broken furniture and the floor had missing pieces under the dining table. Sure it has a french press coffee maker, but can you count it as an amenity if it is broken and non-functional? I think you're getting the picture here.
I contacted the 'host' through the app (not Ruth), who was very responsive. They sent over their 'cleaning team' and changed out the bedding in just a few hours which was great response time, I appreciated it. However, they refused to acknowledge the other issues I raised even after asking for photos, but then ignoring that I sent them. I gave up and enjoyed my stay in London, spending as much time away from the apartment as possible.
Long story short: I've stayed at many AirBnBs and I know they're not hotel rooms. This was the grossest place I've experienced on ABnB by a wide margin. Should you book it? I'd consider it if it was $75/night - maaaybe £75/night. But it looks nothing like the pristine photos lead you to believe - it's beat.
