I also wonder this. I think my listings are fairly priced, but London is not a cheap city, especially when it comes to accommodation. Why would someone spend all that money on flights, Airbnb etc. and not see or do anything while they're here?
I've had this occasionally with guests. One time, it was some newly weds, so I think we can guess why they wanted to stay in their room. I had one girl stay for over a week and hardly leave the bedroom. It was the last stop in a two month tour of Europe, and she said she was tired and just wanted to relax. Okay, fair enough, but it seemed like a wasted opportunity, as well as a waste of money, given that she had never been to London before and ended up hardly seeing any of it.
Probably, it was the nicest room she stayed in during her whole trip (the room was underpriced at the time) and so it was easy to just laze about on the comfy, king sized bed. That's the danger in making a room really welcoming. A more recent guest, who did go out, commented that it was hard to motivate herself to do so. In her review, she wrote, "My room was spacious and very comfortable and I felt quite indolent with all the chandeliers, velvet seats and fluffy cats. Honestly I found it hard to drag myself away every morning!"
It has occured to me also, that sometimes (less experienced) single travellers might have thought it was a good idea to travel solo but then find they don't enjoy it that much. They might feel lonely, scared, intimidated, overwhelmed or just plain bored going out by themselves and end up just hiding in their rooms watching Netflix or whatever.
When I was much younger, I had a stopover in Cairo. I thought I'd see a bit of the city while I was there but soon discovered it was not such a pleasant place for a young woman on her own, so I decided just to stay in the hotel. I had a similar experience in Johannesburg when I was about 20. However, those were just one night stopovers en route to somewhere else and I have visited both those cities on other occasions when I had company. I can't imagine spending days in a foreign city and not going out!
