We own and rent out a little coastal chalet located in Mumbles, Swansea. It is a perfect place to explore Gower from.
We manage it via AirBnb. The url below links to our AirBnb account to check availability and to book etc:-
The price varies with season but is usually between £56 and £65 per night for the whole chalet. AirBnb then add a small surcharge to that.
