I've stayed in about 10 airbnbs, and this was my first negative experience.
On the plus side, the location really was fantastic - very close to the Earl's Court tube station, in a fairly central location. And the room itself was nice. I appreciated having a washer/ dryer and access to a kitchen. But it is not well taken care of.
The flat had not been cleaned when we arrived (we're talking trash on the floor, stains on the unwashed sheets, and wet towels everywhere), and we had to wait several hours before a cleaner arrived. There were also cleanliness issues like actual bugs in the bed (after the sheets had been changed), no trash bags anywhere in the apartment (including in the trashcans) despite specific instructions about what color trash bags were ok to use, and the shower curtain was literally ORANGE with mold.
Check-in was confusing. When we arrived (after the 3pm check-in time), there was no key in the lockbox. We had been given a code to open the box, then we were told the old code had been changed for security, and then it turned out the code had not been updated, and it was the first code that opened it. (And again, after figuring all this out, the box was empty.) So we stood in the street while I tried to make my phone work, when a man (who did not identify himself) walked up to us, asked us if we were there for the airbnb, and just handed us the keys. It was surreal. Also, if a person who worked for this company was there to hand us a key, I am baffled as to why he did not know the apartment wasn't clean?
Communication was generally pretty quick but a little bizarre. No less than 6 different people were in touch with me "on behalf of Eddie." It was a bit strange, and it made me feel like no one person new what was going on, particularly when we were having trouble getting into the flat and then finding that the flat was filthy.
It would be a great little place if it were actually clean and if it was better taken care of - dresser drawers had no bottom and were therefore impossible to use, and the freezer was so iced over that we had to spend about 10 minutes chipping ice off of a drawer so that we could use it. The location is fantastic, and it's a nice little room. But the management was incredibly disorganized and the place needs some attention.
