Overall, the space is sufficient for two people, but not the seven guests as indicated in the listing. For example, the listing had 4 bedrooms, but 2 of them are in the attic and have no A/C (only a small fan). Since we traveled in January (height of summer in Brazil), it wasn't really possible to sleep there. As a result, there are really only 2 beds for use.
The listing included 3.5 bathrooms, but one of them was out of commission as the toilet didn't flush, the second one was upstairs in the non-AC space, and the 0.5 bath is outdoors on the balcony. That meant only 1 bathroom was for use.
I should note the living space also has no air-conditioning, so the few hours we were in the Airbnb, we stayed in our respective bedrooms. There were also bugs in the apartment (ants, small flies, and a dead roach in the bathroom); of course, some small amount of pests are to be expected in an older building, but there were more than expected which made the place feel unclean.
Ultimately, given we were a group of 4, the living space was smaller than we needed (we ended up having to share two beds and one bath). As a result of the small space, the lack of advertised air conditioning throughout the apartment, and the relative uncleanliness, we decided to move to a hotel on the last day.
The host offered us $300 USD cash in compensation to help defray the cost of the hotel, which was a nice gesture. However, the person delivering the cash demanded that in exchange for the $300, we write a positive review in front of him and not to pursue this matter further with Airbnb Support. We did not feel comfortable with this transaction as we did not want to write a false review, so we declined.
