When we booked this room, the Airbnb reviews were very good. But we were pretty disappointed with this stay. The room is inside of a 2 star hotel which is not clear from the listing (I would recommend looking at the google reviews for the Lancaster Court Hotel). We found the hotel staff to be kind and helpful, but there were some uncomfortable rules like leaving your room keys when you left, leaving the car keys if you park there, and the guests need to be let in the front door. Even though the front desk was staffed 24/7, it is a deal-breaker for us to not have the ability to access our room on our own.
The biggest positive was the location, which was very good for exploring London.
All in all, we would absolutely not stay again and would advise other users to research the place fully.
