We stayed there for 5 nights as a family with two adults and three kids. We had enough space for everyone and the apartment was really clean and stylish. We each had 2 towels and the beds had clean sheets. The apartment is close to two metro stations with one being part of the line to the airport (only 2 stations from terminal 1/2/3 and 4 from terminal 4). The area is a residential area with a lot of locals living there and a supermarket right on the other side of the street or -for longer opening hours- close to the station Mar de Cristal where a "Carrefour" is located. For your groceries you have a fridge and a freezer and for preparing everything you have an oven/ stove and a microwave as well as a table grill. For entertainment the TV has a HDMI booth so you can connect your laptop.
Tipps: A nice restaurant/ bar in the area is "La guapa". They serve nice burgers and have nice drinks. We were there over Halloween and had a child with us who wanted to go trick-or-treating. This is obviously nothing you do at private households because 4/4 people didn't give us anything and even got angry at us. But all the local kids went to the shopping center on the other side of the street "Colombia" where everyone got some treats. The phrase "trick or treat" in Spanish translates to "dulce o truco".
