In Summary: Wouldn't recommend.
The shower wasn't usable during the 3 days we were there. When I reported the problem to Filipe, I was quite disappointed by the long response times and the general lack of responsibility or empathy of the situation. I never felt like it was a big priority to get the issue fixed during our stay and unfortunately, I was right. My family had flown 12 hours to Portugal and ended up having to wash their hair in the kitchen sink.
When I asked Filipe for some type of compensation, either monetary (like a small discount) or even just flexibility with check-out time or allowing us to leave our bags in the apartment, he responded that he had evaluated the situation with his team and agreed that it did not require any type of compensation.
Given our experience, I would recommend finding a different airbnb, as there are so many comparable ones. Overall the apartment was fine and in a good location, but if something unexpected goes wrong, I am not confident in the management team of this property to actually help you.
(It's also good to note that the front door is up 10 flights of stairs - no elevator - which really does impact how often you want to be coming in and out)
