We had a long term stay for work and everything was really great. It is in a quieter neighbourhood but with everything you need nearby. The centre is very close with just a few stops in the metro or a short bus ride.
Bus and metro is pretty much at your doorstep
Two large grocery stores, pharmacy, bakery etc very close.
Across the road is Casa de Campo, a large and beautiful park.
The apartment is well suited to a long stay as well.
