Great location, just a few minutes walk from the metro, Praça Comercio and rush Augusta (promenade filled with restaurants, bakeries and shops).
The lack of air conditioning and only one working fan meant we had to sleep with the windows open. The street might be quiet regularly but the night we stayed, there was a movie being filmed and it was extremely noisy (they were filming car chase scenes) so it made sleeping nearly
impossible.
Communication was great, check-in was easy.
