Susana's studio is great. It's very comfortable, light and clean. It has heating, hot water in the bathroom and in the kitchen and a beautiful balcony.
It's also very well located. Las Cañitas is a very nice neighborhood, with lots of restaurants, cafés and supermarkets, and my boyfriend and I felt very safe to walk around at night. The studio is close to the subway and to a big avenue where you can catch buses to different parts of the city!
Besides, Susana is a great host. She is very friendly and helpful, knows the neighborhood well and can give you good tips to enjoy your stay. We would definitely stay in the studio again if we return to Buenos Aires and recommend it to anyone who travels to the city!
