I got really lucky with my recent stay in Brasília. Originally, I had some trouble finding an…read moreupdated, modern hotel with amenities (gym, wi-fi), and then I came across Melia Brasil 21.
It's a big hotel with a handful of different options and I stayed in Bloco D, which appears to be the most updated building. I also booked a room that had access to LEVEL, their VIP lounge of sorts with snacks, happy hour, and the perfect business/meeting area.
My 12th floor room was pretty nice and of the executive variety: king bed, fancy desk, leather reading chair. I have to say, I was pretty happy with it. Even better, the hair dryer is one of the best I've seen in a hotel room. Secret tip: there may be a humidifier in the closet (use this at night!).
The rooftop pool is small and narrow, but it gets the job done if you just need a quick dip. As for the gym, sadly it was under construction during my stay, so I ended up using the makeshift temp gym on the pool floor. There were only 2 dated treadmills and one exercise bike and with no A/C or fan, the space got pretty hot (and dry).
As for the location, it's pretty decent. Walking right outside the hotel, you'll find shops, restaurants, like Fogo de Chao, so in a city where walking places isn't really an option, it's nice to have everything you might need within a few feet.
This is definitely the place I'll stay during future visits to Brasília. And always, I'll stay in Bloco D.
