Our host arranged so we could check in soon after our flight, and met us with keys and a tour of the apartment. She provided suggestions of where to eat and was quick to answer when messaged.

The apartment was exactly as described, and we enjoyed it. As noted, there is noise from the streets in the evening but this was not problematic. It wasn't excessive as the people weren't rowdy (almost no fighting, yelling etc.). As others have commented, the water is not hot for very long, and it takes a fairly long time to heat again. There was WiFi available over the weekend, but not during the weekdays (this was just a nice surprise, as we weren't expecting it).

Overall, I would definitely recommend staying at the Bairro Alto lounge. The location cannot be beat.
