It is a great apartment! First of all view from the apartment on the 20th floor - OMG, it's just so breath taking to see a city, especially at night time! This view is a big plus for this apartment. This place has a kids playground - so it's a good place for families. Also there is a gym and pool. The whole building is secured, so it's very safe. About location - there aren't maybe very interesting things to do near the building, but if you walk like 15 minutes, then there are so many cool cafes around Parque Revolución and further on (another 15 minutes of walk) around Parque de China. And about 40 minutes walk from building there is Parque Bicentenario - it's a huge place, very popular among local people and you can spend there 3-4 hours freely. Supermarket (Soriana) is just 600 meters from building.
