There aren't a lot of these old-style pensiones left in the middle of Madrid, so if you're looking for an authentic Madrid experience that is affordable and central, this is the place for you. A few caveats, beforehand: The building is historic, but it doesn't have a lift, so it does mean a walk up four (quite dark!) floors to the rooms. (Aniceto, the owner, does generously offer to help guests with their luggage, but if stairs are not your thing, it's worth knowing). There's a fair bit of noise on from the street (calle Atocha does have a lot of traffic). That said, the positive bits are very positive. Aniceto and Victoria are extremely helpful and very friendly. The decor is kind of dated, but the rooms are immaculate and the property is very well cared for. It's very close to Atocha Station, the Reina Sofia Museum, and the transit connections are exceptional. Overall, a positive experience - just watch those stairs!
