Oh my, this was a FANTASTIC hotel to stay at in Madrid.
My wife and I took an 8 day trip to Madrid, and booked this hotel because Expedia recommended it, and it was perfect.
It is about as central as it could be, about a 2 minute walk from the Puerta del Sol in the center of town, and from there, it was a 10 to 20 minute walk to almost anywhere, or direct access to the metro.
The staff was fantastic. The one minor problem we had (slow shower drain) was fixed almost immediately after reporting it. The on-site 24 hour free cafe had coffee/tea/chocolate/cookies/fruit/juice any time we wanted it. And the morning surprise of pastries and water hung on the door handle made breakfast (or pre-breakfast) super easy and delicious.
Anyone that I know that plans to travel to Madrid will get this hotel as a recommendation from us. Very impressed, and economical as well. Thanks for a great stay B&B.
