Exceptionally well located, we spent a long weekend in Madrid and were able to walk to everything we wanted to see.
The house is beautifully designed, incredibly stylish. Due to its central location I guess it isn’t “quiet” but it’s worth it to be so central and is far from noisy. One thing to note is that there aren’t any bedroom doors so privacy could be an issue however for us this wasn’t a problem.
I wouldn’t hesitate to stay here again if I found myself back in Madrid.
