I still don't know if Christian speaks English, but I tried to converse mostly in my poor Spanish. He's very helpful and the place a really good base to discover the city. It's a real good value for Santiago as well. The bed is enough for one person, but surely won't fit two. Being able to wash upstairs was a neat feature. The pool however is only accessible after talking to the reception first (didn't try it). The next metro, Santa Lucía, is about 12 minutes walk, which was okay for me. There would be buses close by as well. And most importantly, he saved me on really short notice (3h) from another Airbnb. Muchas gracias Christian, mucho gusto!
