Coming from a first-time AirBnB user, this was a 5 star experience all the way. I know I will inadvertently leave a few things out, but here is what I found:
Check in and check out were simple. The place was very clean. It stayed by myself, but the space can easily accommodate several more people if needed. Good location only a few minute walk from tube stations (including the line going direct to/from Heathrow). TV w apps in case you want to spend a quiet night in. The building also has a lift in case you have a lot of luggage to bring up and down. And a fan in the bedroom for those of us who get hot easily! Couldn't be happier with my experience!
