What a great apartment! I think this might be one of my favorite Airbnbs I've stayed in. It was very well fitted out, the bed was comfortable, the view was great. It's _super_ conveniently located. António made the checkin process completely seamless - he actually spotted me on the street getting out of my Uber, and was very responsive throughout the trip.
There were some small details that I really appreciated. António made a point of showing the things that were unusual during checkin (e.g. the power switches for appliances), and left a bottle of wine behind. The towels were really nice and plush, which is unusual at Airbnbs!
There are also a few caveats worth knowing about the place - nothing that isn't clear from the listing, but just worth highlighting. The apartment has 2 beds; and although I was staying on my own, I could imagine it being a bit cramped with more people (especially because the slope of the ceiling cuts off some of the usable space). And while the flights of stairs are kind of short, it _is_ on the 5th floor (that's 6th floor for you Americans), so you do have a bit of walking to do (and the building is already uphill from a lot of the tourist areas of Lisbon).
I think it's important visitors to know all of that, but that doesn't diminish that this was a great Airbnb that I'd be very, very happy to stay at again if I'm ever back in Lisbon.
