I was very pleased with this Airbnb and it was great value for money. It is very well situated between Paddington and Lancaster Gate underground stations. It was a quiet area with basic shops and several restaurants nearby.
There were some problems over check-in in and access to the internet but these were resolved quickly by the host.
You do get what you pay for but the description is accurate. It is up 4 flights of stairs and the photo gives an accurate impression of the room. The toilet / shower room is incredibly small but manageable.
When I first saw the building I was concerned about noise, but in the 6 nights was only aware of other occupants on 4 occasions.
As a single traveller to London this flat was ideal for my needs especially it's value for money.
