My brother and I rented this apartment for a month. It's a really nice place and in a phenomenal location (3 blocks from a metro, 2 blocks from an outdoor shopping mall, grocery store across the street, and tons of places to eat are all around the neighborhood. You are only about a 10 minute walk to Avenida Honduras, which is packed with bars and clubs.
The apartment itself is also very nice. It is cozy and can sleep about 5 comfortably (with a bed for everyone). The bathroom isn't very big, but it has everything you need.
The balcony is big enough to sit out and enjoy a cup of coffee and take in the great sunsets.
If I'm ever back in BsAs, I will certainly stay here again!
