The checkin took a long time because of the passports, but the staff was very friendly and tried their best to accomodate us at a reasonable speed. I do really appreciate that.
As for the rooms, they were nice and clean with a bidet and decent shower, etc. I have no complaints about the room, we have 4 twin beds and so it was super comfortable.
Regarding the location, it was OK, not far from the border and some facilities, but a little further from the falls than I had hoped. In any case, we had a beautiful view of the city from there.
Breakfast, as was always the case whenever I went to any place in Brazil, was top notch! Loved it, and thank you!
