We had a wonderful visit to Madrid staying in Xuan's apartment. The place is well-located (very close to the La Latina metro station), easy to walk to cafes, etc, but on a side street so it stays very quiet for sleeping (does not get much natural sunlight though - only windows are onto an interior courtyard). The loft bedroom does not have much privacy, but three of us stayed very comfortably there. The shower and bathroom were great (beautiful, good water pressure and temperature), although did not have much privacy (no shower curtain or bathroom door). Overall the apartment worked very well for our purposes, as a centrally located place to explore Madrid from!
