This spot is a true gem, perfect for a romantic getaway, just as advertised.
Matthew's hospitality was top notch - he was very friendly (but gave us our privacy), flexible and easygoing about our schedule, and extremely generous - providing not just the obvious water and toiletries but also wine and fruits.
Note that the Bel Air area is somewhat remote and you'll need to drive / take an Uber to get pretty much anywhere, so again - great for a romantic getaway, complete with your own private yard, beautiful fountain, comfy (electric!) bed and Netflix TV.
