Cute, well-decorated little house. Not a lot of daylight, but on the plus-side perfect for a cosy night in with lots of light fixtures. Check-in and -out is hassle-free and super convenient with a lockbox. The bedroom is spacious with a soft, big bed. The kitchen is very well equipped, although weirdly missing some basics like a simple peeling knife and some more bowls. Minor issue is that all the cupboards are stocked with the host's personal foodstuff so there is no room for whatever you buy. And some things weren't very clean: a plate, cup, a pan all vary degrees of dirty. But I think this is due to the dishwasher, which doesn't do a great job. Also keep in mind the place has no airco, and the room upstairs can become quite warm.
The location is good enough: 3km walk to the centre or a 6€ bolt/uber ride. I didn't find the neighbourhood itself very lively, it's calm but and there are some nice parks/restaurants nearby. Very difficult to park however! And do not park on the little parking lot around the corner: that's residents only! We didn't see it (nor can read Portugese), parked there for 2 hours, and got a big fat fine on the first day (130€). Just a warning :)
However, there were some serious issues too: in case the listing's description hasn't changed yet: there is NO backyard. This is a blatant lie. There is no outdoor area at all. There is a small area with a glass roof at the back. There was also no dedicated workspace (desk). And when we were there (July 2021), there was almost constant construction noise from one house over. Loud and continuous drilling. It turns out the host was aware of the construction, but hadn't mentioned it. Because of these problems, we wanted to change the dates of the reservation but the host refused, claiming he wasn't in the wrong, and wanted us to start a procedure via AirBnB. By not responding in a timely fashion, he managed to drag everything out, forcing us to stay the full duration. Other than that, he was cordial and answered other questions swiftly.
Because of these problems, I can't say this was a positive experience for me and I won't recommend this.
