I booked on the evening that I was wanting to stay (literally 10mins before getting to the property) due to a cancellation on another booking.
I received a response near instantly, thankfully and was advised that the keys were all inside the unit - very kindly the hosts organised and paid for an Uber to deliver their personal keys to me (and wait for me to get in, then take them back)...
It was an absolute god send.
The place is spectacular and in a fab location.
Superb hosting, super stylish pad - 5 stars!
