I stayed at the Brasilia Alvorada Park (which previously belonged to the Blue Tree Hotel chain) for 1 week. The hotel is excellent, it has modern and comfortable rooms, with high speed internet, and a great breakfast with ample options. The hotel restaurant is also very good, with a surprisingly good wine menu. One of the pluses of the hotel is its great swimming pool, perfect for relaxation. The hotel also has a spa which is very well managed and a gym.
The negative aspect is its location, near the Alvorada Palace, in front of Paranoá lake, which is far from everything. You will need a taxi for anywhere you want to go, and it is not near, ie expensive taxi rids. A solution could be to rent a car. Since Brasilia traffic is busy, this means you could get caught into the city traffic jam.
