We had a nice stay at Blanca’s appartement. Very centrally located, clean, tidy and especially great for those who want to explore Madrid. We were with two kids and noise from the street and upstairs apartment did bother us going to bed but that was 9pm-10pm in the evening. If you are not an early sleeper, apartment is good. Easy to check in/check out. Again, with two kids washing machine would have been important to have but if you are not planning to have a real dinner inside, it’s not a problem. Parking around is tough, took us some time to find a spot. If you are using taxi- not a challenge ofcourse!
