The single rate was 43 euros and the double rate was 55 euros. If you look on the Hostal Aguilar web page, the rates are listed. I don't know if they change them according to "high season" or "low season" or if they remain constant throughout the year.

Glad I could be of help! I think it's always useful to read comments from people who have stayed in a certain place, especially when the visits are more recent.

And, it was a pleasure to meet you, too, steve robinson (as well as all the other attendees)! I really enjoyed the MM get together and I will be sure to let you know when I visit Madrid next!
