We traveled to the NB42K in Porto Alegre, when the location is very close to the event approximately 2km, as well as booking was easy, the hotel is really what is in the pictures, but we may have given luck.
Our room had mold, the appears were with moisture, Shower had to turn on only in the hot pq did not heat up much.
I ordered at the hotel a heater pq the air conditioning did not heat up, they said it did not, and a girl from the reception went to look at us and said that the air conditioning was normal and that it was one of the best, but I know how the air conditioning works, and it was not working and did nothing, so it was not very comfortable.
Mancha coffee was ok, bed was ok.
