I stayed in one of the private rooms for 5-6 weeks and had a great time. The hosts are very helpful and not just with the administrative things but anything you need help with. Just ask them. The best thing about the place is that you meet some great people from all over the world and the location is also great. One thing to be aware of is that some of the rooms are facing av. 9 de Julio and can be noisy because there is traffic 24/7. I used earplugs and had no problem with it during my stay.
