Fantastic Paddington location - absentee host.
Pros:
* Location - very convenient to Paddington Station, Hyde Park, local stores, restaurants and pubs.
* Environment - charming
* Quiet - sleeping is comfortable and quiet (unless building fire alarm runs for hours...see below)
Cons:
* Communications - host did not respond to questions in a timely manner. Host phone number link did not connect to anything, in fact AirBnB support also could not contact host and for several hours and called him "non-responsive". The only proactive communication during the stay was warnings not to interact with the neighbors in any way.
* Noise - building fire alarm ran for hours without resolution, other than to sleep best we could with ear plugs.
* Security - the building door was often propped open.
* Shabby - multiple deferred maintenance issues in the apartment. The terrace was downright filthy.
Conclusion: The location is fantastic so this flat will likely always be booked in good season, despite an absentee host and some sub-optimal issues.
