We had a great time at Silveiras Loft. We arrived early so we left our luggage at the Welcome Center in a really nice neighbourhood. The place was clean and we had a bottle of wine to welcome us. It's really well located, in the center of the city, every attraction is close by walk and if you need, the subway is really close. A little grocery just in front of the loft and really nice restaurants around.
We came with our 2 years old son, and the loft is not really planned for a young kid: the street is really noisy and the building is not soundproof. So he was woken up really early by the "night owl". That was the main problem for us.
