I have stayed at Embassy Suites Rosales twice now. The hotel is fine, and the price was reasonable.
The best thing about this place is its location - right in the center of Bogota's gastronomic center. Can't throw a rock without hitting a good restaurant. Less than 2 minute walk to Argentine, Japanese, Mexican, Italian, general Asian, and of course Colombian cuisine.
This is a nice neighborhood, however always be aware of your surroundings no matter where you are in Bogotá. A couple years back I stayed at this place and a colleague was robbed at gunpoint by a fake cop a couple blocks away from the hotel. This is not likely to happen to you in this sector but common-sense precautions are always appropriate in Colombia
