I would definitely stay at Susana's apartment again. Lots of space to accommodate a larger family or group of friends, funky interior design, located in a mostly convenient location, and good communication with the host. A couple of things to consider on the location: on the weekends a nearby bar/plaza can get loud later into the night but there are good shudders to limit the noise; also, while the apartment is near some great neighborhoods, shops and restaurants you have to walk up some steep hills to get to them (I love hills and stairs but someone with limited mobility might find it problematic).
