Hello @Paula and to all,
Oh I am so glad you've asked this question😉 This is a bit of a sore subject for me as I deeply regret that Airbnb do not have "outdoor space" as a filter for guests to narrow down their choices of places to stay.
The only way to show guests you have a garden, a balcony or patio is to show it in the first five pictures but that is just a workaround and pretty unsatisfactory for guests to have to sift through 15 pages of listings in the hope of finding a place that provides an outside space, be it big or small.
All of Airbnb's competitors have this filter and yet on Airbnb, the only option for guests in the current filters is to sort listings by Pool, jacuzzi or BBQ. Not ideal then if you are in a town environment but you want a place with a terrace or balcony!
So yes I provide a lovely balcony with seating for four to enjoy a lovely glass of something special and a table and chairs for 4 and although it's a feature that guests really appreciate, this outdoor space is not deemed great enough feature to appear in the filters for guests😒
A real shame for both guest experience and hosts alike.
