We enjoyed our stay here! We found the Airbnb to be quite spacious and had a great layout. Check in was very easy with clear instructions. As mentioned, there are quite a few stairs to navigate to enter and some are quite narrow. It's not too bad once you've hauled your luggage up though! and it is a well lit stairwell. Another point is the steep incline the Airbnb is situated on if there are any mobility issues in your group. But hills are definitely everywhere in Lisbon!
Overall the location of the Airbnb is pretty good. It's close to the water (beautiful view from the small balcony!), and there are many restaurants and tourist points of interest nearby, including the Time Out Market and Pink street. We did find it a bit loud, at least in the front bedroom, at night and, as expected, the whole building isn't very sound proof, so you will hear your neighbours. Overall though, we did enjoy our stay and look forward to coming back to Lisbon in the future!
