It's a beautiful and unique space. It was close to buses and a 20-minute walk to Boca. There was a great TV, a comfortable bed, and hot water.
The problem was the complete lack of communication. I guess there was an emergency, but my friend who was able to make local calls had to call Julio so that someone could let us in - because he never replied to my messages. Since I never heard from them, I also figured check out on my own.
The man who let us in was very helpful and kind and gave us a tour. The building is remarkable, but I'm not sure I'd stay here again.
