Clean, comfortable, everything you need to enjoy the downtown of Madrid. Like any flat in the area, it’ll be a bit noisy at night, so I’d recommend earplugs/running the fan/etc if you’re a light sleeper. Elevator made getting luggage upstairs very easy. Beds were comfortable and the heaters in each bedroom made sure it was nice and warm even in January. Having two bathrooms is a huge plus, although the one is quite small. Highly recommend this stay!
