Isabel was helpfull on the check in. And we had a great time at your space.
The place is cool, totally well located (walking distance to all major attractions at Madrid - really!) and the double windows are really good to keep the place as quiet as possible!
I was travelling with 2 kids and we love it. If I am back to Madrid will stay there!
There are some points for improvement:
1) 4 people taking bath - the last one got a cold bath (even going faster)
2) could have more glasses to drink wine
3) the sofa is not that comfortable - but for 2 kids it was ok
