Overall this is a nice place in a very nice part of London within walking distance of shops, restaurants, Underground stations, and the Chelsea FC stadium. Just read all the rules of the house first. If you peruse the listing of this flat you will see under check-in it says "Flexible". But that is deceptive. If you open up the house rules and scroll down you see that you can, in fact, check-in whenever you prearrange with the host, but you will be charged £40 if you want to check-in after 19:00 (7:00 pm), £65 if after 22:00 (10:00 pm), and £100 if after 0:00 (midnight). When I gave my host my flight information she said I would be at the flat around 22:00 and sent me a request for the £65, which I had no choice but to pay upfront. Our flight arrived 30 minutes earlier than expected and travel didn't take as long as the host said it would. So we arrived at the flat at 20:30 (8:30 pm) and there was nobody to let us in. We knew the host was out of town and that she'd arranged for someone else to be there, but we did not have that person's contact information, so we had no choice but to haul our luggage to a pub and wait 90 minutes to go back. We did receive a curt message from that woman at 21:36 that said, "I'm waiting for you in the flat. Where are you? When you here?" (sic) I have stayed in about a dozen AirBnBs in the last few years and this is the first one that did not have a keypad where we could let ourselves in with a code provided by the host. I don't understand why this would not be an option on this flat. There were no special instructions that we could not have figured out on our own. And the woman who checked us in didn't speak English well enough for us to understand any of her instructions anyway. But I guess that simple solution would mean that the host would not be able to charge extra to someone whose travel plans into London don't get them there early in the day.
