Paula's place is very accurate in the description. It is within walking distance to all the major tourist sights and we didn't have to take metro once while in Madrid. The apartment is sparkling clean, while small but very comfortable. Only thing you need to beware is that the apartment sits on top of a local bar which at times can get loud at nights. It didn't bother us much as the noise dies down past 12 PM. Paula is very responsive and provide clear instructions to the apartment. I highly recommend it.
