Kathi's place is located 5 mins away on foot from Paddington station, where you can access several restaurants and supermarket inside the station. It's less than 30 mins access to most of everywhere in London.
Kathi, the host here, is very well communicator on Airbnb, and was trying to set everything up right.
The flat is on the 4th floor without lift. We had a buggy for 1.5 yo son, and we left it on the ground floor so it was easier.
If you are looking for a place in Paddington, this is it.
