Lujan's studio was nice. It was clean and her mother was their to help my brother and I arrive. She spoke some English, which was really helpful as we didn't have much Spanish between us.
I'm not a BA native, so I could be wrong here, but for us it felt like we were quite a distance from Palermo Soho, the location it is listed as being in. And the problem with this was that walking home after being in bars we walked through a couple of rough streets. We were two guys and we felt a bit intimidated once or twice.
Other than that, the location was good, opposite a huge supermarket and a good place to base ourselves to explore the wonderful city.
