ARC Arenales is a modern long-stay apartment complex, with a large room and a small kitchen if you want to make your own meals. House keeping is every few days, just right for such a long stay.
The two issues
* The internet was unusable. It was fast when it worked, but it kept dropping every few minutes, making even email or web browsing unusable.
* There is a pool. but it's a tiny kiddie pool. Don't believe the pictures.
