Pros:Room was very clean, comfortable, & large. Room service was very quick. The hotel is about 20 minutes from GRU. Free airport shuttle from hotel to airport was great. The complimentary breakfast was amazing. If you need an extra late checkout they allow you to book 1.5 nights. There is a Walmart nearby that we took a taxi to if you need to pick up anything. There's also a really great park called Bosque Maia (I think) where we brought our toddler to play and she loved it. There are also some really good restaurants near the park. Hotel is perfect for an airport stay over but I wouldn't stay there longer than a couple of nights.
Cons:The restaurant is expensive and the food isn't that good (other than the breakfast). You need to contact the hotel to make arrangements for the shuttle from airport to hotel. When I did this they told me to call them as soon as we landed, but I didn't have a phone that worked in Brazil so that was impossible. We took a taxi instead that cost R$60. The taxi driver told us that when you do use the hotel's shuttle to get you at the airport they take forever to arrive. The hotel's location isn't near anything touristy really but it's right near the airport. The location isn't very walkable so we ended up taking taxis everywhere.
