I will say overall the place is misrepresented by the photos. It is much smaller than you will expect. In fact one of the bathrooms has the smallest sink I’ve ever seen. When we arrived near midnight, which they knew, there was nothing in the house to eat or drink. I’m not looking for a meal but at least a bottle of water and something for a snack would have been a nice touch.
Regarding the neighborhood I’ll say this- you are in walking distance to the metro and many attractions so that’s super convenient. However, it’s not a neighborhood for children or families. If you want a nice peaceful vacation with the family, this is not the place for you. But if you want a convenient location for a few days to see the city of Madrid, then it could be right for you. It’s not a bad price but just know that it’s not as nice of a situation as you might seem.
