Matias was very welcoming and allowed me to extend my stay by two days with a discount. He even offered to let me stay an extra night for free on the living room couch since someone else was taking my room!
There are 4 or 5 rooms with a shared kitchen and 2 shared bathrooms, so it had more of a community feel. The other guests were also very welcoming and we shared coffee and went out together a couple of nights.
The kitchen is stocked with spices, utensils, coffee... Pretty good if you are planning to cook some of your meals at home. Overall, was a great place to stay in downtown Buenos Aires!
