Antonia was a really good host, from the first moment she gave me the keys and took the time to show me how to use them (little details that I appreciate). After stating the rules of the house (wich are the same published here, read them!) and leaving my luggage, she gave me a little tour arround the building giving me directions to grocery stores, laundry and touristic places. The location is close to everything you could need when arriving a new city
During the month I was there, Antonia was always asking me how was everything and if I nedded something else.
The room is big and well ventilated, the house is really nice and clean, it is cozy in a minimalistic way. It's located inside a big building wich makes it calm, quiet and much fresher than the outside (I was there during november, late spring).
It was the perfect place to work on my tesis and to discover the city of Buenos Aires.
Yes, the rules are as strict as everybody says, but nothing unreasonable. It's just a matter of being clean, organized and have common sense; in perspective, I think it helped me a lot that I lived there. The kind of shower in the appartment was totally new for me, but nothing you can't get used to after a couple days, actually, now I think it is better that my regular shower.
In conclusion, after a few days I felt at home. I strongly recommend staying at Antonia's place.
