Tobias was a great host! He was quite communicative and always responded to messages quickly. He even stayed up late to meet us at check-in at midnight and allowed us to extend our check-out time on the last day. The apartment was perfect for a weekend for two guests. Tobias even warned us about the small bathroom, but it did not prove to be problematic at all. The apartment is a great location--less than 10 minute walk to the metro and quick access to city center. I would recommend to a friend and revisit if I return to Madrid.
