THE GOOD:
(1) Catherine was excellent in providing all the required communications to enter / exit the building.
(2) For budget travel, this place is fine and has the essentials you would require.
THE NOT SO GOOD:
(1) Building from the outside was disappointing. I wouldn't have booked if I was aware of the exterior / pictures provided on the listing. I booked this from the 'suitable for business travel' shortlist on Airbnb but this certainly gave me the wrong expectation.
Airbnb policy doesn't require hosts to include this information because technically, you are renting the inside, not the outside of the building. So if you care about the exterior, just check with the host first as this will help manage guest expectations.
(2) Feedback to Catherine - if you are planning to have tradesmen attend the Airbnb while the guest is occupying it, not a problem but please provide more notice than 1 hour. In all fairness, when I advised Catherine I was not comfortable with this - she cancelled the tradesmen but for that period in between it caused some concern on my end.
