Unfortunately we had a few disappointments with this Airbnb. Before travelling to Lisbon I read the apartment's listing which stated: 'At the day of arrival, we usually ask the guests to contact us as soon as they are coming to the house. We or our staff will be(...)waiting for you with the keys.'
I messaged Mario asking if I should therefore just text when we were on our way, he didn't reply to this part of my message, so I made the fair assumption that someone would be able to let us in whenever we arrived, presuming it was at a reasonable hour. However when we got to Lisbon airport at lunchtime and I texted the number on the Airbnb listing and we received no reply. After a long while waiting and calling with no reply I managed to get hold of Mario on Airbnb messenger and he told me he was in Sintra. It took about two hours from this point for him to get back to us, meaning we had wasted nearly whole afternoon of our holiday by this point. He wasn't very apologetic and I can't quite understand why Mario would travel to Sintra on a day when he knew he had tenants arriving, not without checking in with us first to find out our arrival time.
The air conditioning in the flat was also very weak, the fridge door kept falling off, and one of the beds was incredibly creaky - so much so that we couldn't sleep in it without waking ourselves up every thirty seconds and had to switch beds. If you had two couples staying in the flat it might prove problematic!
With all that said, the terrace is absolutely beautiful with stunning views and the flat was otherwise clean and lovely.
