Very nice, tidy and quite big apartment. Perfect for a couple or someone alone. Location in very nice area(only downside is that to reach the front door you will have to walk a lot of steps. But that's what you need to expect in all of Lisbon).
Good communication regarding the smartlocks.
Something to keep in mind is that because of the restaurant underneath the airbnb, it's not nice to open some windows due to the frying smell. But if you're away for the day you will not notice this at all.
