I had the opportunity to stay at Daniels place, it is located in the heart of Madrid. The space is good for 2-4 people. There is limited hot water for any given timeframe so ensure you are the first to shower, leave the cold water to others....LOL. The bathroom is a bit small but manageable. The Internet access was great, make sure you read the instructions behind the door. Overall, this is the perfect spot if you are visiting Madrid, it is located near everything. A+++ for Daniel.
