The location couldn't be better. Very close to Plaza Mayor and lots of other things, you can walk anywhere. There is one bedroom and one bathroom (the listing says 2 bathrooms) and a sleeping sofa in the living room. The agents replies to messages right away and is very helpful sorting out other things, like transportation and events. He also offered an early check in (at 9 am), which we took for an additional 30 euros, which was a good thing as we were tired from our travels.
The most important thing I feel like I need to mention is DO NOT LET CHILDREN IN THE SHOWER as it is incredibly easy for the water to get SCALDING. I had a burn myself trying to prevent her from getting injured.
