A great location, really close to the Reina Sofia, and only 10 mins from Atocha railway station. We were able to walk to all the major sights very easily. The apartment was very clean and the beds were very comfortable, however it was a little tired round the edges and was missing a kettle. Also the sink in the bathroom leaked every time we used it.
Was great for 3 of us but any more would be a squeeze.
