AirBnB has been my de-facto landlord for about half of the last 18 months, all over the world. I've had two sub-par experiences (both in London fwiw) and one really-actually-bad one that nearly turned into a fistfight with the "host", who was illegally renting the place and furious that I, quite reasonably imho, contacted the condo desk to be let into the space.

AirBnB gave me a refund and a 10% off coupon for that last one. Overall I've been happy with it; must just be luck.

Nice to have my own apartment again though. The nomad life is fun, I just wanted a home after awhile.
