If you want to be in the heart of Madrid, Vin's terraced apartment is the place to be to experience what it's like living like a local. The apartment is as noted but pay attention to the fact there is no elevator, the kitchen is very small with basic equipment, and the bathroom ceiling slants sharply which could create an issue when showering. If you can ignore the 24 hour street noise, the two terraces are what makes this place worth staying at.
