This is a pretty apartment, just like the photos, with one of the best equipped kitchens I've ever seen in an Airbnb. The bath was great. The apartment itself was spotlessly clean. However, the location, while very central, is dirty - little fruit flies would come in immediately if we opened the windows, and there was excrement and trash on the street, which led the bad smell the other reviewer mentioned. This was a surprise, as the rest of Lisbon we visited was not like this.
If you have ANY difficulty climbing stairs, or are above 6ft 2" - this is not the apartment for you! These are not western stairs - they are very narrow and incredibly steep - more like a ladder with a low ceiling. Carrying a suitcase up them was difficult (and the gentleman who checked us in only assisted us when we actually got stuck on the third flight) and carrying one down again was downright terrifying! I wish this had been made clearer in previous reviews.
I would usually let all of this slide and still award a 5 star review if the hosts were friendly, or at a minimum, responsive. However, I don't know what went wrong for our stay, as they are superhosts, but for us the hosts were not very responsive or hospitable. We even selected the apartment due to their own statement - saying to contact them for anything at all, even your silly questions. But instead we were rarely responded to, even when there were real issues. We appreciate this was a stressful time (with the coronavirus upsetting everyone) but it was made even more stressful for us due to the lack of information and dialogue throughout our stay. Perhaps they were just having a bad week, like the rest of the world.
