We stayed here, two friends from AMS and BER. The flat is a charming, renovated rooftop flat in a block of similar apartments in Bairro Alto. A very nice spot to work remotely for us for a few days to escape the gray covid vibes of northern Europe.
Note if you are new to Lisbon - that if using taxi, you will need to get off nearby and walk the last few hundred meters to the flat as it is a pedestrian area. Same for leaving of course.
Also highly recommended to venture out to other areas for best food and drinks experience as many of those area spots in Bairro Alto are tourist traps. The place downstairs for example is pretty questionable. I guess it just depends what you're looking for ;).
Besides that, checkin was nice and easy. The rooms and beds are comfy and nice for the price. The view is really spectacular from the balcony. We got clean towels after a few days, and no huge complaints.
That said, some things worth clarifying:
1 - the flat is directly above a live music bar, which shuts daily at 2 AM. so expect a fair bit of noise, even with the windows closed. and on the weekends, things are a bit later closer to 4 AM. I think I was expecting more normal cafe and bar noise, but this was more like actual party vibes so just be aware of that if you are a light sleeper or have picky tastes in music. Luckily I am a heavy sleeper.
2 - there is also lots of construction lately in the daytime, so expect a fair bit of noise from that too, especially if the windows are open.
3 - the 2nd bed is clearly in the common living room. i knew that in advance, but just wanted to clarify, as one of the photos makes it appear as a 2nd, separate room. can be a bit confusing when viewing on mobile.
4 - wifi is nice and fast but drops out sometimes, so if you are a digital nomad, definitely bring a backup hotspot.
