Excellent location, just a few blocks from Parque España and close to many restaurants and cafes. The desk and chair were great for working, and I had no problems with wifi. I enjoyed the balcony, and there are nice touches throughout the loft. Aline was quick to respond, and helped me out with a couple of requests.
A note if you're tall: there's a steel structural beam running across the middle of the loft. It's probably not a problem for most people, but I'm 6'4" (1.93m) and had to watch my head around it. There are other units in the building that are available sometimes if this might be an issue for you.
