Fantastic apartment, location and host!
The apartment has everything you could need. AC, wifi, balcony, TV with english and spanish channels, friendly security downstairs, blankets, towels, even a blowdryer!. It is very comfortable for 1 or 2 people.
The location is right in the heart of the city. There is a subway line less than a block away, and a vast majority of the buses can be taken from 2 blocks away (near the oblesik). There is a shop downstairs and a mini supermarket across the road (carreefour express). It can start to be a bit noisy in the mornings around 9:30am on the weekdays but you are in BA, should be awake exploring!
Josefina is an extremely gracious and flexible host and was available to me always if I had any questions. I would recommend this apt again.
