Marvelous place, very quiet, stylish, elegant.. our room was super comfortable, we loved the queen size bed as well as enormous bath.. it was hard to leave the room for the sightseeing:) self check in is extremaly convenient, kitchen is spacious, what else one can need. as for the location - it is very quiet and safe, although you will probably use public transport to get to the city center (place is located 3 stops from sao bento), by walk it shall take you about 35 minutes. ah, and take uber to the airport, it costs only 12 euro:)
