I found São Luis' hotels to be a bit more expensive than what I expected. This taken into consideration, I'd say what you get at Brisamar is a very fair deal. The service is fine, rooms are very clean, breakfast is very good, and the pool is very welcome as it is always very hot in Maranhão. Location is good, and I was able to walk to several very good eateries (Cabana de sol, Peti´s Caldos, etc). Locals say, however, that the city is not very safe, especially after sunset. I had no problems, though.
The only aspect which could be improved is putting air conditioning in corridors and reception area.
