Claudia is a fantastic host. She is very warm and accommodating. She did everything she could, so I would be comfortable.
The room is a little cramped, but it is comfortable, it has a nice desk space, and...(a big plus) is very private -it has a separate entrance to the apartment, so you can come and go as you wish. Bathroom is also cramped, but no deal breaker.
The neighborhood has several pluses...very safe, very close to public transportation, and very close (a short walk) from Recoleta and it´s Cemetery. For students its´s close to the UBA Law Faculty and Medical Hospital. Also there are plenty of gyms, restaurants, convenience stores and supermarkets 1 or 2 blocks away.
