I spent a week here while in Sevilla. It's been well designed and maximises the space with lots of homely touches and everything you'd need. I was part working so the desk up on the mezzanine was a perfect place and allowed me to separate work from play, with decent WiFi. It's naturally cool, so I hardly needed to use the a/c.
Location wise it's perfect, central, yet really quiet, and everything is within walking distance, with some great bars/restaurants very close.
I'd highly recommend staying here while I'm Seville.
