I only know about the Doubletree Parque 93 location. I have stayed there half a dozen times and really enjoyed the property. It has been two years since my last visit but there was a lounge on the top floor that was indoor/outdoor and only available to elites so I am not sure why your information shows there is no lounge. I spent a lot of time in the lounge with friends and co-workers. It is a delightful lounge.
The rooms are spacious and quiet. The neighborhood borders some fun restaurants and shops just a few minutes walk away near Parque 93. There are so many accessible areas within a 10 minute walk from the hotel for example La Zona Rosa which has popular and high-end shops and restaurants. I never felt unsafe in a small group or even by myself, but it is also my opinion that being by yourself in a foreign country should be minimized, use the buddy system if you can. I had ample access to Uber and Taxis from Parque 93. I never had a bad experience at this location and prefer it over the Bogota JW Marriott for example.
